In his evening video address, President Volodymyr Zelenskyy confirmed the use of long-range ATACMS missiles.
"Today I am especially grateful to the United States. Our agreements with Joe Biden are being implemented very accurately - the ATACMS have proven their worth," the president said.
Earlier, The Washington Post suggested that the Ukrainian Defence Forces may have used US ATACMS missiles against Russian troops for the first time, attacking Russian aircraft at airfields in Berdyansk and Luhansk.
