As Wednesday draws to a close in Kyiv and in Moscow, here are the key developments of the day:

A theater sheltering civilians was bombed in besieged Mariupol, Ukrainian officials say. Russia denies the airstrike. Mariupol's city council shared images of a smoldering building, saying hundreds of residents had taken refuge inside and the number of casualties was not yet known. Elsewhere in southern Ukraine, Melitopol Mayor Ivan Fedorov, captured by Russian troops last week, has been freed.

Ukrainian President Volodymyr Zelenskyy addressed U.S. Congress, calling on it "to do more." Specifically, Zelenskyy continues to push for a no-fly zone over Ukraine, which most U.S. lawmakers and the Biden administration do not back. President Biden, meanwhile, approved $800 million more in security assistance to Ukraine and vowed to send more weapons. He also called Russian President Vladimir Putin "a war criminal."

A top Ukrainian negotiator says Ukraine and Russia might be moving closer to a possible cease-fire. Some Russian officials have also hinted that the two sides may be closer to a deal, but Putin has not signaled a readiness to pull back forces.

The United Nations' top court in The Hague has ordered Russia to halt its military operation in Ukraine. The International Court of Justice said evidence did not support the Kremlin's justification for the attack. Its rulings are binding, but countries have ignored them in the past.

Russia is facing a debt-payment deadline that could mean a historic sovereign default. The country needs to pay $117 million in interest payments on two bonds that are denominated in dollars, but Russia has lost access to much of its foreign reserves.
