WASHINGTON, D.C.: The United States will provide an additional $500 million in financial assistance to Ukraine to help it sustain salaries, pensions and other government programs, a Treasury official said, while the beleaguered country fends off Russia's invasion.

The official was not authorized to speak publicly ahead of the announcement on Thursday, when Treasury Secretary Janet Yellen is scheduled to meet with Ukrainian Prime Minister Denys Shmyhal, along with Deputy Secretary Wally Adeyemo and Ukrainian Finance Minister Serhiy Marchenko.
