US military seizes Iran-flagged ship trying to pass strait of Hormuz blockade
The US military has attacked and seized an Iranian-flagged container ship that attempted to get past an American blockade near the strait of Hormuz, the first such interception since the blockade of Iranian ports began last week. Iran’s joint military command said Tehran would respond soon and called the US seizure an act of piracy that violated the ceasefire that has been in place since 8 April. The news threw into question Donald Trump’s earlier announcement that US negotiators would head to Pakistan on Monday for another round of talks with Iran. That had raised hopes of extending a fragile ceasefire set to expire by Wednesday, but Iran has not confirmed it will attend. In a post on X, US Central Command said US marines departed the USS Tripoli assault ship by helicopter and rappelled on to Touska on Sunday. The post included a video of the marines onboard the helicopter. The Guardian, April 20

French prosecutors summon Elon Musk over sexualised AI deepfakes on X
Billionaire Elon Musk has been summoned for a voluntary interview in Paris on Monday as part of a French probe into his social media platform X, though it remains unclear if he will appear. French authorities issued a summons for Musk in February as part of an investigation, launched in January 2025, into allegations that X's algorithm was used to interfere in French politics. The probe was later expanded to include an investigation into X's AI chatbot Grok's dissemination of Holocaust denials and sexual deepfakes. In early February, French prosecutors searched the Paris offices of X, in what the social media giant - which has denied any wrongdoing - slammed as "politicised" raids and an "abusive judicial act". At the time, Paris prosecutors also summoned Musk and then-CEO Linda Yaccarino for voluntary interviews as the "de facto and de jure managers of the X platform at the time of the events", a move Musk called a "political attack". Yaccarino resigned as Chief-Exec of X in July last year after two years at the helm of the company. France 24, April 20

The insider trading suspicions looming over Trump's presidency
Throughout US President Donald Trump's second term in office, traders have been betting millions of dollars just before he makes major announcements. The BBC has examined trade volume data on several financial markets and matched them to some of the president's most significant market-moving statements. It found a consistent pattern of spikes just hours, or sometimes minutes, before a social media post or media interview was made public. Some analysts say it bears the hallmarks of illegal insider trading, whereby bets are made by people based on information that is not available to the general public. Others say the picture is more complicated and that some traders have become more adept at anticipating the president's interventions. Follow the link to five of the most significant examples.

Keir Starmer battles for Downing Street future amid Peter Mandelson vetting scandal
Sir Keir Starmer will battle for his Downing Street future on Monday as he seeks to explain to MPs how Lord Peter Mandelson became UK ambassador to the US despite failing security vetting. The prime minister’s statement in the House of Commons will come ahead of testimony on Tuesday by Sir Olly Robbins, who was sacked last week as the head of the Foreign Office over the vetting scandal. Starmer, who has rejected calls to resign, will insist he did not know about the vetting verdict and blame Robbins for the “unforgivable” act of not disclosing that Mandelson had not passed. But the former mandarin is expected to tell the Commons foreign affairs committee on Tuesday that by putting in place mitigations to deal with the grandee’s perceived conflicts of interest, he had addressed the red flags raised in the vetting process. Robbins will also argue that the Constitutional Reform and Governance Act 2010 made civil servants rather than ministers responsible for vetting. Financial Times, April 20

Two teenagers arrested over arson attack at London synagogue
Two teenagers have been arrested in connection with an arson attack at a synagogue in north London over the weekend. A 17-year-old boy and a 19-year-old man were arrested overnight after the attack at the Kenton United Synagogue in Harrow on Sunday. A “bottle with some sort of accelerant had been thrown through the window” and smoke was seen inside a room, police had previously said. No injuries were reported, but there was minor damage to the front of the premises after a bag containing several bottles with fluid was set alight in the doorway, said the force.

Japan issues tsunami warning after major earthquake
Japan issued a tsunami warning for hundreds of kilometres of its north-eastern coastline on Monday after a major earthquake struck the Aomori and Hokkaido prefectures. The quake, which was logged by the Japan Meteorological Agency with a preliminary magnitude of 7.4, struck at 4.53pm local time. There have so far been no reports of injuries or other damage from the quake, which was powerful enough to rattle buildings roughly 850km south in Tokyo. Tsunami waves as high as three metres are expected to arrive in parts of the affected area over the coming hour, according to a warning broadcast on Japan’s NHK. Residents of the regions under tsunami alert were told to immediately evacuate to higher ground. Financial Times, April 20

Lebanon’s state agency reports Israeli shelling after ceasefire begins
Lebanon’s state news agency reported Israeli shelling on several towns in southern Lebanon after the ceasefire came into effect at midnight local time. The towns of Khiam and Debbine were struck by artillery fire, NNA reported, adding that Israeli overflights were also ongoing in the Bekaa Valley and other parts of southern Lebanon. Meanwhile, Beirut’s skies convulsed with celebratory gunfire and heavy RPG launches in the moments after the 10-day truce came into effect. Pro-Hizbollah supporters gathered in the southern suburbs of the capital, waving the group’s signature yellow flags and hoisting up photos of its leaders. Local media showed traffic heading to southern Lebanon building up. It was not clear how many residents of southern Lebanon would return home since the last main bridge connected north to south was destroyed by Israel on Thursday. Financial Times, April 17

Macron, Starmer chair meeting to mull European post-war mission in Strait of Hormuz
French President Emmanuel Macron and UK Prime Minister Keir Starmer on Friday will chair a meeting of allies to consider sending a multinational force to ensure security and free-flowing trade in the Strait of Hormuz once the current conflict between Iran and the US and Israel ends. Iran imposed the blockade on the critical shipping bottleneck as soon as the US and Israel launched the war against the Islamic republic on February 28, leading to a surge in global energy prices. Even with a shaky ceasefire in place, the US is now imposing its own blockade on Iranian ports. European leaders are now worried that if the blockade continues, consumers will feel the effects through higher inflation, food shortages and flight cancellations as jet fuel runs out. The leaders joining Starmer and Macron from 1200 GMT for the meeting - which will mostly be held via video - are due to call for a return to full freedom of navigation and address the economic consequences of the blockade.

Cuts to overseas aid will worsen shocks to global economy, David Miliband says
Cuts to overseas aid by countries, including the US and the UK, risk stoking global economic instability amid the humanitarian crisis resulting from the Iran war, David Miliband has said. The former British foreign secretary and head of the International Rescue Committee said the US “abandoning” of its aid programme under Donald Trump would worsen shocks to the global economy that would impact poor and wealthy countries alike. Miliband also said he regretted that Keir Starmer’s government was slashing the UK’s aid budget, because supporting the world’s poorest was morally the right thing to do and a “good investment for Britain”. “An untended humanitarian crisis is an incubator of political instability. We are in a more connected world than ever before,” said the former Labour minister. “The Iran war shows how connected we are, but the connections go the other way [from poor to rich countries], too.” Speaking to the Guardian at the International Monetary Fund and World Bank meetings in Washington, Miliband said the Middle East conflict would increase global poverty and risked displacing millions of people.

Starmer sacks top civil servant over Peter Mandelson vetting failure
Sir Keir Starmer appointed Lord Mandelson as Britain’s ambassador to the United States even though he had failed government security vetting. The prime minister, who insisted for months that “due process had been followed” and that Mandelson had been cleared for the role by the security services, was accused by the Conservatives of misleading parliament. Vetting officers had recommended that the disgraced peer should not be given the job but this was overruled by officials in the Foreign Office, who rubberstamped the appointment. On Thursday evening Starmer sacked the top civil servant at the Foreign Office over the vetting scandal. Sir Oliver Robbins lost the confidence of the prime minister and Yvette Cooper, the foreign secretary, it is understood. The Times, April 17

Finance ministers and top bankers raise serious concerns about Mythos AI model
Finance ministers, central bankers and financiers have expressed serious concerns about a powerful new AI model they fear could undermine the security of financial systems. The development of the Claude Mythos model by Anthropic has led to crisis meetings, after it found vulnerabilities in many major operating systems. Experts say it potentially has an unprecedented ability to identify and exploit cyber-security weaknesses - though others caution further testing is needed to properly understand its capabilities. Canadian Finance Minister François-Philippe Champagne told the BBC that Mythos had been discussed extensively at the International Monetary Fund meeting in Washington DC this week. "Certainly, it is serious enough to warrant the attention of all the finance ministers," he said. "The difference is that the Strait of Hormuz - we know where it is and we know how large it is … the issue that we're facing with Anthropic is that it's the unknown, unknown." BBC news, April 17

US private credit firm backs loans for World Cup ticket flipping
A boutique private credit firm has its eyes on a lucrative trade ahead of the Fifa World Cup this summer: lending to an online platform that aims to flip tickets of sought-after football matches for large profits. Eagle Point Credit Management has recently increased its $50mn financing package to Sports Illustrated Tickets - a sister company of the sports magazine - to help fund its plan to purchase World Cup tickets and resell them with huge mark-ups. The profit potential has convinced Eagle Point to sign off the loan, which amounts to the total cost of the tickets, meaning that if Sports Illustrated buys $1mn worth of World Cup tickets, it would lend a full $1mn. “Normally you would never lend at 100 per cent [loan-to-cost],” said Thomas Majewski, founder and managing partner of Connecticut-based Eagle Point, which manages $14bn in assets. “But World Cup tickets are typically worth up to three times their face value, so the reality is that we are lending at a 35 per cent loan-to-value ratio.” Financial Times, Aprill 17
