WASHINGTON (AP) — Ukrainian President Volodymyr Zelensky on Sunday will visit the Pennsylvania ammunition factory that is producing one of the most critically needed munitions for his country’s fight to fend off Russian ground forces.

He is expected to go to the Scranton Army Ammunition Plant to kick off a busy week in the United States shoring up support for Ukraine in the war, according to two U.S. officials and a third familiar with Zelenskyy’s schedule who spoke on the condition of anonymity to provide details that were not yet public. He also will address the U.N. General Assembly annual gathering in New York and travel to Washington for talks on Thursday with President Joe Biden and Vice President Kamala Harris.
