Matteo Salvini shrugs off critics who say policy reminiscent of fascist past

Matteo Salvini vowed to turn “words into action” in his drive to root out and expel thousands of nomadic Roma from Italy as he shrugged off critics who said the far-right interior minister was adopting illegal policies reminiscent of the country’s fascist past.

Salvini, who has seen a jump in his approval ratings in the little under three weeks he has been in office, has called for a new census of Roma and for all non-Italian Roma to be expelled as part of his .

Jeremy Fleming’s comments can be seen as riposte to EU threats to end UK access to security databases

Britain supplied key information to help break up terrorist operations in four European countries in the last year, one of its intelligence chiefs revealed on Tuesday, as the UK upped the ante in the growing row over post-Brexit security.

The director of the surveillance agency GCHQ, Jeremy Fleming, speaking on a visit to Nato headquarters, also stressed other European countries had benefited from classified intelligence shared by the UK on cyber-threats.

Exclusive: Jens Stoltenberg says US and Europe must work to avoid breakdown in western unity

• Europe and North America need to stay united – now more than ever

The head of Nato has warned that the deep divisions between the US under Donald Trump and its European allies are not going away and there is no certainty that the transatlantic relationship and its military alliance will survive.

Against a backdrop of Trump’s open baiting of the German chancellor, Angela Merkel, over immigration and her domestic difficulties, Jens Stoltenberg has called for all Nato members to work to avoid a disastrous breakdown in western unity.

Military advance comes after UN envoy fails to broker ceasefire with Houthi rebels

Saudi-backed Yemeni government forces have captured the airport at Hodeidah and have started preparations for the more complex task of capturing the city and its port nine miles (15km) to the north. The port is critical to the supply of aid to the rest of the famine-struck country.

Confirmation that the airport on the southern outskirts of the city had been seized after three days of fighting came from both TV pictures and eyewitness accounts. At least 40 Houthi fighters who had held the airport were killed, but most retreated into the city, preparing to fight a potentially intense street-by-street campaign that could endanger tens of thousands of civilians.

Markets dropped across the world after Trump threatened to impose $200bn more in levies on Chinese goods

• Business live: trade war fears escalate

The news roiled global stock markets as investors feared that escalating tensions could trigger an international trade war.

Government also resubmits bill to criminalise those deemed to be helping illegal immigration

The Hungarian government has stepped up its anti-immigration measures with plans to introduce a 25% tax on aid groups it says support migration.

Viktor Orbán’s administration has been among the most hostile to immigration in Europe. His Fidesz party was re-elected in a landslide victory in April, promising to crack down on non-governmental organisations it says support migrants.

150,000 bees stolen near Tessenderlo in latest incident, as interest in hobby grows

Dirty tricks by rival beekeepers have been blamed for a rise in hive thefts in Belgium after huge growth in interest in the hobby.

Following the disappearance of 150,000 bees from hives near the Flemish town of Tessenderlo, keepers have been advised to keep a keen eye on their insects and alert the police to suspicious activity.

Judges say ruling party is tightening its grip through threats and hate campaigns

Three high-profile Polish judges have complained of a “state-led campaign of intimidation and harassment” against them, as Poland’s ruling party tightens its grip on the judiciary.

Since taking power in 2015 the Law and Justice party (PiS) has assumed direct oversight of state prosecutors and the judicial body that appoints, promotes and disciplines judges, as well as the power to dismiss and appoint court presidents, who wield considerable power and influence in the Polish justice system.

Report warns that swift progress in our ability to manufacture viruses is making us vulnerable to biological attacks

The rapid rise of synthetic biology, a futuristic field of science that seeks to master the machinery of life, has raised the risk of a new generation of bioweapons, according a major US report into the state of the art.

Advances in the area mean that scientists now have the capability to recreate dangerous viruses from scratch; make harmful bacteria more deadly; and modify common microbes so that they churn out lethal toxins once they enter the body.

North Korean leader meets Chinese president a week after Kim’s summit with Donald Trump

One week after holding a summit with the US president, Donald Trump, the North Korean leader, Kim Jong-un, has met the Chinese president, Xi Jinping, his third visit since March.

On Tuesday, the Chinese state broadcaster CCTV showed Kim and Xi holding talks at the Great Hall of the People in Beijing, usually used for formal state visits. Analysts believe Kim is in China to brief Xi on the summit, seek economic assistance, as well as pay deference to Beijing, which is eager to emphasise its role in talks between North Korea, the US, and South Korea.

As data shows one in every 110 people is displaced, UN special envoy Angelina Jolie warns of ‘terrible human consequences’ of Syria’s aid shortfall

The number of people forced to flee their homes rose to a record high in 2017, with 16.2 million people newly displaced around the world. The figure includes people who have been displaced for the first time, and those who have been forced from their homes multiple times.

The figure of 68.5 million displaced people – 3 million higher than the total population of the UK – includes 25.4 million refugees, 40 million internally displaced and 3.1 million asylum seekers.

Exercise planned for August put on hold while US and North Korea continue denuclearisation talks

The United States and South Korea have cancelled a major military exercise scheduled for August, a week after Donald Trump said he would end the “war games” in a surprise concession during his summit with the North Korean leader, Kim Jong-un.

The Pentagon said Operation Ulchi Freedom Guardian would not take place, while Washington and Pyongyang continue to discuss denuclearisation following Trump’s historic meeting with Kim in Singapore last Tuesday.

Japan Airlines and All Nippon Airways now refer to Taiwan as a Chinese territory on Chinese-language websites

Japan’s two largest airlines have changed “Taiwan” to “China Taiwan” on their Chinese-language websites, officials said Tuesday, a move likely to please Beijing but anger the self-ruled island.

The change, which was made last week, is meant to accommodate customers, Japan Airlines and All Nippon Airways said.

Argentina’s president once talked of forcing slums out of the city – now he wants to deliver residents the deeds to their land. But will it help?

“It was really bad in there – I mean, it’s literally a ruin,” says Romina Vargas of Argentina’s most famous abandoned building, where she once lived. “There was lots of contaminated water on the lower floors, there were no sewers, and kids would come and take drugs inside. It’s good that it’s coming down.”

Built in the 1930s and later championed by president Juan Domingo Perón, the 14-storey building in south-west Buenos Aires was intended to be the largest hospital in Latin America; a cornerstone of Perón’s grand populist vision for Argentina. But construction stopped abruptly in 1955 with a military coup. The abandoned colossus at the edge of the capital became known as the White Elephant.

Joel Cánovas uses Instagram to document his passion for rescuing discarded tiles as part of his one-man mission to salvage a century of Catalan heritage

Joel Cánovas was sipping a beer on a patio in Barcelona when a piece of rubbish caught his eye. A section of hydraulic cement tile – the once-ubiquitous flooring material used in homes around the city for a century or so from the mid-1800s – had been discarded during a home renovation.

Cánovas picked up the tile, and a passion was born. Spotting tiles in dumpsters throughout Barcelona, Cánovas soon began to document his discoveries on Instagram as The Tile Hunter (@i_rescue_tiles).

The booming market for products for ‘urban skin’ reflects anxieties about the health impacts of living in cities – but is it all just a marketing gimmick?

Fiona Westerhout talks about her skin as though she is giving directions in a familiar neighbourhood: oily around the T-zone, dry cheeks, sensitive with the occasional breakout.

Westerhout, 29, had just started blogging about skincare when she and her partner moved from Perth in Western Australia to Shanghai in May 2016. There she found a new cause for skincare concern: pollution.

There are just 178 registered architects in this rapidly urbanising country, where buildings frequently collapse. But more professionals may not be the solution

Sitting outside the office of her architecture firm in the industrial area of Kampala, Uganda, Doreen Adengo remembers the last major building collapse in the city.

A four-storey building opposite Makerere University collapsed in 2016, injuring dozens and killing four people.

The Trump administration’s ‘zero-tolerance’ policy has led to almost 2,000 children being separated from their families

In April, the US attorney general, Jeff Sessions, announced a “zero-tolerance” policy, stating “our goal is to prosecute every case that is brought to us”. Under the Trump administration’s new enforcement policy, every migrant who crosses the border illegally – even those seeking asylum in the US – is subject to criminal prosecution.

No serious injuries after incident at Southgate tube station shortly after 7pm

Police are dealing with a reported explosion at an Underground station in north London after reports that a suspicious package had been found, they have said.

Country says tennis star, who faces bankruptcy proceedings, is not one of its diplomats

The Central African Republic has denied that Boris Becker is one of its official diplomats and said a passport the former tennis star claimed should give him diplomatic immunity from bankruptcy proceedings in the UK is invalid.

“The diplomatic passport that he has is a fake,” the foreign ministry’s chief of staff, Cherubin Moroubama, told Agence-France Presse. He said the document’s serial number corresponded to one of a batch of passports stolen in 2014.

As a chorus of condemnation builds, defenders are finding unusual ways to back a policy that seems indefensible

On Monday, the conservative news site Drudge Report filled its famous, all-caps lead story slot with the headline “BORDER BATTLE: USA TAKING IN 250 KIDS PER DAY”. Next to the story was a photo of young children holding guns, implying that the children separated from their parents are gun-toting criminals.

The children in the photo were not traumatised minors who crossed the US-Mexico border with their parents. They weren’t even from Central America – they were Syrians. The photo had been taken in Syria in 2012 by photojournalist Christiaan Triebert, and was a blatantly misleading attempt to try to find some way to make the border policy seem legitimate.

The Trump administration’s horrifying child separation policy demands that Canada scrap the Safe Third Country Agreement

Last July, a woman from El Salvador arrived at the Fort Erie border crossing in Buffalo, New York, seeking refuge in Canada. The woman, known only as E, was accompanied by her two young daughters, one still young enough to be fed from a bottle. She threw herself on our mercy, filing a refugee claim based on her fear of being deported by the US to her home country, where she says she had been raped by gang members who harangued her family and threatened to kill her.

Because E arrived through the US, she was subject to the Safe Third Country Agreement, which stipulates that a foreign national seeking asylum must do so in the first “safe” country they arrive in. The agreement was signed in 2004, and since then, the landmass of the US has functioned as a bulwark against Canada’s lofty promises that the persecuted, the terrorized and the survivors of war are welcome here. E and her children had escaped to the US in 2016, so her claim was denied.

Abdull Grafar Ghulami was suddenly taken to Kentucky from Manus Island as part of the Australia-US refugee deal. Now he is forging a new life, despite the weight of the past and four lost years

It is a hot and sticky 25C in Louisville, Kentucky, and the young man is dressed accordingly in a polo shirt, bermuda shorts, long white socks and shoes. Like a local, Abdull Grafar Ghulami refers to the city as “Luhvul” and points out that aside from thoroughbred horse racing and Kentucky whisky, Louisville’s claims to fame are as the home of Muhammad Ali and Colonel Sanders.

Ghulami, 24, is proudly driving an older model car. He smoothly navigates the sharp turns of the city’s overhead highway maze. The GPS tracker he consults is the only outward indication that he is not yet entirely at home in this city.

Calls for prime minister Peter O’Neill to visit restive Southern Highlands province, amid anger over election result

Riots that erupted last week in Papua New Guinea could turn into a full-scale conflict, locals have said, as anger and chaos grip the Southern Highlands province.

In the last week, protesters incensed by the failure of a court challenge relating to an election result have set fire to a commercial plane, government buildings and the home of the local governor, as well as ambushing two police cars.

The photographer behind the viral image that exposed the anguish of Trump’s controversial border policy speaks out

Photographer John Moore, whose viral image of a weeping two-year-old girl at the US border has become the potent symbol of the outrage over Donald Trump’s controversial “zero tolerance” policy, including family separations, knew what he had captured was “important”.

What he could not guess, however, was how great an impact his picture would have on the debate as it was published around the globe.

Nearly 40% of all guns are in hands of US citizens, according to report that says rich countries hold more weapons than poorer nations

Latest statistics show the proliferation of privately owned guns is on the rise, with wealthy countries outstripping developing and war-torn countries.

In a detailed report, weapons watchdog the Small Arms Survey has researched the numbers of guns across 230 countries.

Young people are all but invisible in the justice system, facing ill treatment at the hands of those who should be protecting them

The legendary editor of the Guardian newspaper CP Scott famously declared in 1921 that “Comment is free, but facts are sacred”. Unfortunately, when it comes to hard evidence on how many children are locked up in prisons, detention centres, migrant and refugee camps, rehabilitation units or other institutions across the world, the facts are more scarce than sacred.

There is no single source of accurate data for these figures and estimates vary widely between 15,000 and 28,000 in Africa alone, but common sense dictates that the numbers are likely to be worse than even the highest approximations.

British firm races to produce bananas resistant to fungus sweeping global plantations

A British company has joined the race to develop a banana variety resistant to diseases and climatic changes that threaten to disrupt the availability of the country’s favourite fruit – or even kill it off altogether.

The UK alone consumes more than 5bn bananas a year, while the fruit is a staple food in many poor countries and accounts for an export industry worth $13bn (£9.8bn) a year.

Japan urged to examine payment made by Kirin subsidiary at height of ethnic cleansing campaign in Rakhine state, which firm claims was for victims

The Japanese government has been urged to investigate “immoral” payments, made by a subsidiary of one of the country’s most popular breweries, that appear to have gone to Myanmar’s military.

Kirin Holdings Company has admitted its offshoot, Myanmar Brewery, made a payment late last year, during the height of the ethnic cleansing campaign against the Rohingya population in Rakhine state.

One oil spill from the Trans Mountain pipeline would destroy Squamish territory. So much for Trudeau’s promise

• Oil pipelines can be positive for indigenous people. Here’s how

The Trans Mountain pipeline expansion project is no ordinary pipeline. This project, which the government of Canada has just decided to nationalise, will travel more than 1,000km from northern Alberta through unspoiled wilderness to end at the port of Vancouver. The port is on the Salish Sea, part of the hereditary territory of the Squamish People. The Salish Sea is home to some of the world’s largest wild salmon runs. Majestic orcas swim in the waters and feed on the abundance.
