President Trump is holding talks with his Ukrainian counterpart, Volodymyr Zelensky, at the White House - with the visitor hoping for increased US support against Russia. Mr Zelensky is expected to ask the US for long-range Tomahawk cruise missiles.

Also in the programme: there's been a last-minute adjournment of an agreement to reduce carbon emissions from global shipping; and how an ancient Roman gravestone found its way into the back garden of a New Orleans house.
