US President Joe Biden and several other world leaders have "reaffirmed their commitment to providing Ukraine security and economic and humanitarian assistance,” White House press secretary Jen Psaki told reporters, according to Reuters.

Biden spoke with some allied leaders in a secure video call from the White House Situation Room.

In their 90-minute video call, Biden and the allies discussed their diplomatic engagements and coordinated efforts to further impose "severe economic costs to hold Russia accountable," Psaki said.

The leaders agreed to continue their discussions in the future.
