What's gone wrong at Nike? How the world's sportswear giant lost its mojo It's been a difficult few years for Nike. The largest sportswear brand on the planet, named after the ancient Greek goddess of victory, has been losing of late. The one-time industry disruptor is now the establishment and in the middle of a tricky turnaround plan aimed at clinging on to market dominance. Nike's latest financial results show signs a turnaround strategy put in place by company veteran Elliott Hill, who was coaxed out of retirement two years ago to lead the firm, is working - but the pace of change is more marathon than sprint. However, its recovery has been dented by the loss of football star Kylian Mbappé, who ended his 20-year association with the brand last week to join fast-growing Swiss rival, On.

Vladimir Putin has said Russia will use all weapons at his disposal if it considers it has come under direct attack in its Baltic exclave of Kaliningrad. Addressing the Valdai foreign policy forum, Putin insisted Russia was not threatening anyone and merely responding to statements by Western leaders that Moscow was preparing for war in 2029 or 2030. Throughout this week, Russia has accused Nato of preparing to blockade its territory, which borders Lithuania and Poland, warning that it would even be prepared to use nuclear weapons if the West tried to cut off Kaliningrad from the rest of Russia. Nato has sought to calm the situation, stressing it is a defensive alliance and urging Moscow to stop its nuclear threats. Western allies have faced a surge in so-called hybrid warfare incidents blamed on Russia, particularly in Poland and the Baltics in recent months.

Britain is in talks with EU partners to release additional strategic fuel reserves, including diesel, if needed, the BBC understands. The talks come after President Donald Trump threatened to ban diesel exports from the US in a bid to reduce record prices at the pumps for Americans. Diesel prices in the UK also hit record highs this week and are hovering just under 200p per litre, according to motoring organisation the RAC. The US is a vital supplier of diesel to the world, exporting between 1.2 and 1.5 million barrels per day, with experts warning a ban on shipments abroad could put further pressure on prices in other countries. We're thinking about it very seriously, Trump said of an export ban at the weekend.

Two Russian drones have hit one of Kyiv's main bridges, bringing public transport in the Ukrainian capital to a halt and signalling a new stage in Moscow's attacks. The Pivdennyi or Southern bridge came under fire as a metro train was travelling across. Passengers described how dust from a blast wave entered their carriage through the ventilation system. The Pivdennyi bridge is one of the main arteries across the Dnipro river dividing western and eastern Kyiv. Kyiv's bridges had not been hit before Thursday's strikes - and despite a dramatic explosion close to a main support section, city authorities said preliminary checks did not find any critical damage to the structure.

President Donald Trump's push to rename AI may be behind an unprecedented rise in registrations for domain names in Slovenia, according to its official national registry. The president wants AI to be called super intelligence - or SI - the same initials used by Slovenian websites. She said the scale of activity in late September was unprecedented compared to the previous 12 months. President Trump called for the technology to be renamed during his speech to the United Nations General Assembly in New York on 11 September. The use of the word artificial makes it sound fake, he said.

Artificial intelligence (AI) could trigger financial market shocks and the UK needs to be prepared for them, the governor of the Bank of England has warned. Andrew Bailey said the central bank is watching the huge amounts of money being invested in AI very carefully and cautioned that not everybody always wins. The money that has been spent on and loaned to AI firms over the last few years in the hope of large returns is causing markets to value some of them as multi-trillion dollar businesses. Asked if he believed an AI bubble could burst, Bailey said: You could see some correction of asset prices at some point. He was speaking exclusively to the BBC about what the risks and benefits of AI could be for the UK economy.

Image caption, The hikes are part of immigration policy changes introduced to manage Japan's growing foreign population Japan has raised fees for foreigners looking to reside in the country, with the cost of permanent residency going up 20 times to 200,000 yen ($1,270; £955). Those seeking permanent residency must now also meet new income, pension and Japanese-language requirements. Long lines formed outside immigration offices earlier this week as applicants sought to beat the fee hikes, with Tokyo's main immigration bureau reporting wait times of over seven hours. The fee increases are part of a series of changes to Japan's immigration policy under Prime Minister Sanae Takaichi, which aim ito manage its rapidly growing foreign population. In July, Japan implemented a five-fold increase in visa fees for all foreigners - its first visa fee hike in 50 years.
