President Joe Biden on Wednesday announced an additional $800 million in weapons and other assistance for Ukraine as officials warned that Russian forces are preparing to intensify attacks in the east.

Biden announced the package after a call with Ukrainian President Volodymyr Zelenskyy, the White House said. Zelenskyy said in a video address that he was grateful for the support.

The new aid comes as the Organization for Security and Co-operation in Europe found that Russia has committed human rights abuses and broken international humanitarian law in its invasion of Ukraine.

The report said experts found a pattern of abuses. The U.S. ambassador to the organization said it includes evidence of the direct targeting of civilians, rape, executions and attacks on hospitals. Biden accused Russia of "genocide" Tuesday.

There is no chance at the moment for a humanitarian cease-fire, U.N. Secretary-General Antonio Guterres said. He said the U.N. has made a number of proposals to Russia about the possibility of local cease-fires, humanitarian corridors and the evacuation of civilians, “and we are waiting for an answer.”

• The presidents of Poland, Estonia, Latvia and Lithuania traveled to Kyiv and met with Zelenskyy. Egils Levits of Latvia said that they saw evidence of Russian atrocities and that the entire command chain would be held responsible.

• Mariupol Mayor Vadym Boychenko has said at least 100,000 people still need to be evacuated out of the besieged port city.
