Here are the latest developments in Russia's war in Ukraine:

- US bans Russian oil -

President Joe Biden announces a ban on US imports of Russian oil, gas and energy, saying Ukraine will "never be a victory for Putin".

Britain also says it will phase out Russian oil imports by the end of this year.

Before the move is announced, the price of Brent crude, the international benchmark, soars by more than five percent.

- Evacuations begin -

Ukraine begins evacuating civilians from the northeastern city of Sumy under a deal with Moscow to hold fire and set up humanitarian corridors in cities besieged by Russian forces.

Dozens of buses ferry the evacuees to the city of Lokhvytsia, around 150 kilometres (93 miles) to the southwest in Ukrainian-held territory.

Kyiv and its Western allies had rejected a previous proposal to evacuate Ukrainians to Russia.

- Ceasefire -

Moscow announces a ceasefire in Kyiv, the northern city of Chernihiv, the besieged southern port of Mariupol, Ukraine's bombed-out second city of Kharkiv and Sumy.

Ukraine accused Russia of violating the ceasefire in Mariupol, where civilians are trapped in "apocalyptic" conditions, according to the Red Cross.

- Thousands of Russians killed: Pentagon -

The United States estimates between 2,000 and 4,000 Russian soldiers have been killed in the nearly two-week-old invasion. Russia has not given an updated toll since March 2 when it announced 498 troops had been killed.

- 21 killed in airstrike -

At least 21 people, including two children, were killed in air strikes on Sumy on Monday night, hours before the evacuations began.

Thousands attempt to board packed trains out of Odessa, Ukraine's main port which is also bracing for attack.

Three adults were killed and three children wounded when an anti-personnel mine exploded under their car on a road in the Chernigiv region north of Kyiv, Ukraine's ombudsman said Tuesday.

- Two million refugees -

The UN says the number of people fleeing the war now tops two million.

Poland alone has received 1.2 million people.

- Zelensky slams unkept 'promises' - 

Ukrainian President Volodymyr Zelensky denounces what he calls unkept "promises" by the West to help protect Ukraine.

"It's been 13 days we've been hearing promises, 13 days we've been told we'll be helped in the air, that there will be planes, that they will be delivered to us," he said.

- China's Xi urges restraint -

Chinese President Xi Jinping urges "maximum restraint" over Ukraine but stops short of condemning the Russian invasion in a video summit with the leaders of France and Germany.

- 'Call Russia' campaign -

A group of Lithuanians launch a bid to get Russians abroad to call 40 million of their compatriots and tell them what is happening in Ukraine. 

Russia has severely restricted reporting of the war on its territory.

- Shell quits Russia - 

Energy giant Shell says it will stop purchasing Russian crude oil and shut down its operations in the country.
