Ukraine calls for worldwide support against month-long Russian invasion

We're marking a month since the start of Russia's invasion of Ukraine as President Volodymyr Zelensky urges people around the world to show their support for his embattled country.

An emergency meeting of Nato leaders including Joe Biden are due to meet in Brussels shortly - we'll be speaking to the former US ambassador to the western military alliance.

And we'll go to Lviv in the west of Ukraine to meet one of the country's greatest pianists inside the city's shuttered opera house.
