Ukraine fired a US-supplied, long-range ballistic missile at a Russian target last week and overnight, the Associated Press reports.
They cited US officials as saying America secretly sent Army Tactical Missile System missiles in an aid package last month.
They were used to hit a Russian military airfield in Crimea last week and Russian troops in another occupied area overnight.
One of the officials said the US is providing more of these missiles in a new
military aid package signed by Joe Biden today.
They new give Ukraine nearly double the striking distance — up to 190 miles.
For months, the US resisted sending long-range missiles out of concern that Kyiv could use them to hit deep into Russian territory, escalating the conflict.
Separately, the vice chairman of the US joint chiefs of staff has told the Associated Press "the time is right" to provide long-range missiles to Ukraine.
