Russia has used the Oreshnik ballistic missile as part of a massive overnight strike on Ukraine. Four people were killed and 25 others injured in Kyiv on Thursday night, where loud booms could be heard for several hours, setting the sky alight with explosions. It only the second time that Moscow has used the Oreshnik, which was first deployed to hit the central city of Dnipro in November 2024. Russia's defence ministry said the strike was a response to a Ukrainian drone attack on Vladimir Putin's residence in late December, which Kyiv denies carrying out . While the ministry did not specify what had been the Oreshnik's target, shortly before midnight (22:00 GMT) videos began circulating on social media showing numerous explosions on the outskirts of the western city of Lviv.

Ofcom urged to use'banning' powers over X AI deepfakes The government has urged the regulator Ofcom to use all its powers - up to and including an effective ban - against X over concerns about unlawful AI images created on the site. Ofcom's powers include the ability to obtain a court order to prevent third parties from helping the Elon Musk-owned platform from raising money or from being accessed in the UK. This follows an ongoing backlash against the use of X's AI Grok to digitally remove clothing from images of people. The possibility there could be sexualised images of children raised very specific concerns in government. Addressing concerns over sexualised images of adults and children produced by Grok, Prime Minister Sir Keir Starmer said: This is disgraceful.

Campaigners have accused the government of dragging its heels on implementing a law which would make it illegal to create non-consensual sexualised deepfakes. It comes amid a backlash against images created using Elon Musk's AI Grok to digitally remove clothing - with one woman telling the BBC more than 100 sexualised images have been created of her. It is currently illegal to share deepfakes of adults in the UK, but new legislation that would make it a criminal offence to create or request them is still not in force despite passing in June 2025 . But it is unclear whether all of the unclothing images created by Grok would fall foul of this law. The BBC has contacted the government for comment.

Elon Musk's Grok AI appears to have made child sexual imagery, says charity The Internet Watch Foundation (IWF) charity says its analysts have discovered criminal imagery of girls aged between 11 and 13 which appears to have been created using Grok. The AI tool is owned by Elon Musk's firm xAI. It can be accessed either through its website and app, or through the social media platform X. The IWF said it found sexualised and topless imagery of girls on a dark web forum in which users claimed they used Grok to create the imagery. The BBC has approached X and xAI for comment.

We were fired, and we're owning it - here's how to find a new job that works for you The new year is a natural time to reflect, and for many of us, that involves thinking about our careers. Kristina O'Neill and Laura Brown are both editors who lost their jobs after restructures, and they initially thought it was the end of the world. I poured my heart into the role... I believed in the values we promoted. Yet, when it came to me, those values weren't there, says Laura.

Trump calls for US military spending to rise more than 50% to $1.5tn President Donald Trump has called for US defence spending to be increased to $1.5tn (£1.1tn) in 2027 for what he called these very troubled and dangerous times. That would be more than 50% higher than this year's $901bn budget, which was approved by Congress in December. This will allow us to build the Dream Military that we have long been entitled to and, more importantly, that will keep us SAFE and SECURE, regardless of foe, Trump said on social media on Wednesday. In separate posts, the president said he would crack down on payouts to bosses and shareholders of major US defence contractors unless the firms speed up deliveries of armaments and build new manufacturing plants. Economists have previously warned that the gap between US spending and its income has reached unsustainable levels.

It looks like a golden chandelier and contains the coldest place in the universe. What I am looking at is not just the most powerful computer in the world, but technology pivotal to financial security, Bitcoin, government secrets, the world economy and more. Quantum computing holds the key to which companies and countries win - and lose - the rest of the 21st Century. In front of me suspended a metre in the air, in a Google facility in Santa Barbara California, is Willow. Frankly, it was not what I expected.

President Trump's favourite word is tariffs. He reminded the world of that in his pre-Christmas address to the nation. With the world still unwrapping the tariffs gift from the first year of his second term in office, he said they were bringing jobs, higher wages and economic growth to the US. What is less debatable is that they've refashioned the global economy, and will continue to do so into 2026. The International Monetary Fund (IMF) says that although the tariff shock is smaller than originally announced, it is a key reason why it now expects the rate of global economic growth to slow to 3.1% in 2026.
