These are the key events so far from Wednesday, March 3, the eighth day of Russia’s invasion of Ukraine:
Russia advances in the south
Russian forces take the Black Sea city of Kherson in southern Ukraine, a significant victory for Moscow after a string of military setbacks. Russian forces also surround Mariupol, where “terrifying fighting” is reported.
Ukraine’s second city Kharkiv continues to come under severe Russian shelling, with police and university buildings among the latest struck.
‘Massive explosions’ heard in Kyiv
Ukrainian media say several “massive explosions” have been heard in the capital, Kyiv, triggering air-raid sirens amid fighting on the outskirts of the capital.
UK says Russian convoy ‘delayed by staunch resistance’
The miles-long Russian military convoy north of Kyiv remains more than 30km (18 miles) from the capital as a result of it having been delayed by “staunch Ukrainian resistance” and logistical issues, the United Kingdom’s defence ministry says.
First Russian toll
Russia says 498 of its troops have been killed in Ukraine, its first declared death toll since President Vladimir Putin launched his invasion on February 24. The true number of casualties on each side is not known. The United Nations has recorded at least 227 civilian deaths, but says the real toll is likely higher.
War crimes probe
The International Criminal Court’s chief prosecutor says an active probe into possible war crimes in Ukraine “will immediately proceed” after his office received the backing of 39 countries.

Russian jets enter Swedish airspace
The Swedish Armed Forces say four Russian fighter jets entered Sweden’s air space to the east of the island of Gotland in the Baltic Sea.

Wounded Russian troops in Belarus
The Associated Press, citing doctors and residents, said Russian soldiers wounded in fighting around Kyiv are being ferried to a Belarus hospital near the Ukraine border.
