Ukrainian President Volodymyr Zelenskyy has made appealed to U.S. President Joe Biden for the United States to designate Russia a "state sponsor of terrorism," the Washington Post reported Friday, citing people familiar with their conversation.

Biden did not commit to specific actions during that call, the newspaper reported.

The label can be applied to any country that has "repeatedly provided support for acts of international terrorism," the newspaper said, citing a State Department fact sheet. The list currently includes four countries: North Korea, Cuba, Iran and Syria.
