Here are the latest developments from the ongoing Russia-Ukraine conflict

Moscow said Tuesday that Russian forces had opened a humanitarian corridor for Ukrainian troops who agreed to lay down their arms to leave the embattled city of Mariupol.

Russia said on Tuesday it was expelling 36 diplomats from two European countries in retaliation for similar measures taken against Moscow’s foreign envoys over the Kremlin’s military operation in Ukraine.

Russia on April 19 called on Ukrainian forces to “immediately” lay down arms and issued a new ultimatum for the defenders of the besieged port city of Mariupol to give up their resistance.

China told Russia it will continue to increase “strategic coordination” with it regardless of international volatility, the foreign ministry said in a statement on Tuesday.

Ukraine said Tuesday there would be no humanitarian corridors to evacuate civilians in the country for a third consecutive day because there has been no agreement with Russia.

U.S. President Joe Biden will on Tuesday hold a call with allies to discuss the Ukraine crisis, including how to coordinate on holding Russia accountable, the White House said. The United States is set to approve another $800 million in military aid for Ukraine, less than a week after announcing a package of the same amount, U.S. media reported Tuesday.
