Why is Russia attacking Ukraine? Can anything be done to stop Vladimir Putin? And just how far could the conflict go?

In this special emergency podcast, our team of experts from around the world tell ITV News presenter Nina Hossain what you need to know as they assess the ramifications of Russia's military assault on its neighbour.

From the Ukrainian capital Kyiv, our Europe Editor James Mates describes how the conflict started and where it is heading in the early hours.

Our Correspondent Neil Connery in Moscow explains why Vladimir Putin's aggression is "22 years in the making", before US Correspondent Emma Murphy outlines from Washington the potential response led by President Biden and the regrets at the first attempt to prevent Russia crossing the Ukrainian border.

International Affairs Editor Rageh Omaar then explains why the Putin world view is so different from the West and why the shockwaves from this overnight attack and the sanctions on Russian money will be felt right across the UK.
