A U.S. Marine veteran was killed in Ukraine last week, according to an activist group in the country. 

Cooper "Harris" Andrews, 26, was hit by a mortar April 19, during a battle for a crucial road to Bakmut, the Resistance Committee said in a statement posted on social media. 

He died while defending evacuees alongside others who were killed, the group said.

Andrews joined the Foreign Legion, a group of foreign fighters assisting Ukrainian forces since being invaded by Russia, according to social media posts.

He served in the Marines from January 2017 to Jan. 16, 2022, a U.S. official told Fox News. He was stationed in Camp Lejeune, North Carolina, before being discharged as a ground electronics transmission systems maintainer and traveling to Ukraine. 

"We can confirm the death of a U.S. citizen in Ukraine. We are in touch with the family and providing all possible consular assistance," the U.S. State Department said in a statement. "Out of respect for the family’s privacy during this difficult time, we have nothing further to add."
