The war in Ukraine has gathered pace on the economic front as the West considers whether to ban Russian oil. Russia has retaliated saying, if that plan is approved and goes ahead, it may close its main gas pipeline to Germany - which accounts for about 40% of supplies to the EU. The main issue with such a move is there are no easy substitutes if supplies are disrupted. Germany has already suspended key Russian gas pipeline Nord Stream 2 following the invasion of Ukraine. But a potential ban on oil prompts a warning from Russia’s Deputy Prime Minister Alexander Novak. A "rejection of Russian oil would lead to catastrophic consequences for the global market", he says, and would cause prices to more than double to $300 a barrel. But this remains on the table for the US and its allies as a further way of punishing the country that continues its mission to conquer Ukraine. Further Russia-Ukraine peace talks have failed.
A third attempt at a ceasefire to allow evacuations of civilians also didn’t materialise as Russian shelling continued in besieged cities, Ukraine says. Officials also pointed out while Russia said it was ready to reopen humanitarian corridors on Tuesday, the offer was rejected because the routes would only lead to Russia or its ally Belarus. Civilians are continuing to flee Irpin, near Kyiv, with more than 1,000 people being led to safety. "Everything is bombed," said one woman trying to escape. To ensure the safety of citizens the UN is calling on Ukraine and Russia to ensure they can flee fighting. The UK has issued more visas to Ukrainian refugees amid criticism from France that it needs to do more to help. Later, Ukrainian President Volodymyr Zelensky will speak via video link to the House of Commons in what’s been described as a historic event. He will be making his statement on the day a fourth round of peace talks are due to take place. Follow developments on our live page.
Our latest explainers on the conflict:

Concerns mount over global food prices which could soar due to the war in Ukraine. It could have a catastrophic impact on the world's poorest, says the head of the World Food Programme, David Beasley. Russia and Ukraine - once dubbed "the breadbasket of Europe" - export about a quarter of the world's wheat and half of its sunflower products, like seeds and oil. Ukraine also sells a lot of corn globally. Prices are already going up and analysts warn the conflict could impact the production of grains and even double global wheat prices. It means more people face potential starvation worldwide, Mr Beasley says. He adds that the number at risk had already risen from 80 million to 276 million in four years before Russia's invasion. "Just when you think hell on earth can't get any worse, it does," he adds.

The energy crisis has seen more than 25 suppliers go bust. One supplier - Bulb Energy - was on the brink of collapse last year due to soaring wholesale gas prices but was rescued by the government. The Treasury set aside £1.7bn to buy the gas needed until the end of this tax year in April, which meant 1.6 million customers haven’t had to worry about moving suppliers. Part-nationalisation was only meant to be temporary as it was hoped a buyer would be found. But government officials admit this is unlikely given the current situation, which could cost taxpayers billions more pounds. Read more here.

Russian President Vladimir Putin set out his "key demands" to halt the invasion of Ukraine, reports the Daily Telegraph, as Kyiv rejected Russia’s offer for citizens to leave. This was because the "humanitarian corridors" led into Russia, the Guardian says. Calls for the UK to do more to help the growing refugee crisis is covered by the Metro and the i. The Daily Mail, meanwhile, leads with a "new dash for gas" to stop Mr Putin holding the West "to ransom". And the Sun features a little girl who, it says, had a defiant message for the Russian president. Read the newspaper review in full here - it contains some distressing images.

Killing Eve star Sandra Oh is pretty choosy about her roles but she jumped at the chance to voice a character for Pixar's latest film, Turning Red. She plays the mother of a 13-year-old girl who’s doing pretty well - that is until she has a rush of hormones. So, why did Oh decide this film was for her? Find out here.
Next to a different kind of star - one from outer space. A shooting star's been captured, in what’s been described as a one-in-a-million shot, when a family wanted a photograph with the Northern Lights. They were all smiles, unaware the star was flying over their heads, which meant everyone but them saw it. Read more here.
And finally to an angler who had a bit more luck. He not only saw, but also managed to record a fireball meteor as the large bright light flew through the sky during a fishing trip. Take a look.
