It's past lunchtime in Kyiv, and if you're just joining us, or want a recap, here's what's been happening today:
Ukrainian officials say they believe 300 people may have died in the bombing of a theatre-turned-shelter in the city last week, though such numbers are difficult to verify independently
Ukraine has had some recent success in re-taking towns and defensive positions east of the capital, Kyiv, UK defence officials say - though fighting continues across the country
Four people have been killed after Russian strikes hit a medical centre in Kharkiv, according to local police; the city is under heavy bombardment but has not fallen
US President Joe Biden has been in Europe this week, and he's due to meet Ukrainian refugees in Poland - near the border with Ukraine - later today
And on his trip, Biden issued a warning to Russia if it uses chemical weapons in Ukraine, amid concerns they could be deployed
The EU, meanwhile, has signed a deal with the US over liquefied natural gas, as Europe attempts to wean itself off Russian fuel supplies it has relied on in recent years
Casualties continue to mount: Ukrainian officials say 135 children have been killed since the invasion began, while the UN says mass graves in the battered city of Mariupol might hold up to 200 bodies each
Thousands remain trapped in Mariupol amid daily bombardments, creating a humanitarian crisis - and the local mayor says it would take years to rebuild the destroyed city
