President Petro Poroshenko has reacted to the U.S. decision to supply Javelin antitank missiles to Ukraine.
In a statement posted on Facebook, Ukrainian President Petro Poroshenko confirmed the delivery and said his country continues "to strengthen our defense potential in order to repel Russian aggression."
"I am sincerely grateful for the fair decision of [U.S. President] Donald Trump in support of Ukraine, in defense of freedom and democracy," Poroshenko wrote. "Washington not only fulfilled our joint agreement, it demonstrated leadership and an important example."
