Ukrainian's president accused Russia of carrying out genocide after officials said Russian aircraft bombed a children's hospital on Wednesday, burying patients in rubble despite a ceasefire deal for people to flee the besieged city of Mariupol.
House Speaker Nancy Pelosi, who spoke with Zelenskiy, said he raised the need for future assistance -- including aid for refugees and rebuilding -- that will cost more than the $13.6 billion package now making its way through Congress.
“We are going to have to see what all of us have to do working together, NATO and other countries,” Pelosi said.
Fears are mounting the capital will be encircled, with AFP seeing Russian troops pressing closer.
Overnight, the Ukrainian General Staff warns Russian forces are continuing their "offensive operation" to surround the city.
A total of 1,207 civilians have died in a nine-day Russian siege of the port city of Mariupol, its mayor says in a message.
At least 35,000 civilians were evacuated from besieged Ukrainian cities during a 12-hour ceasefire on Wednesday, President Volodymyr Zelensky says.
