On February 25, 2021, the United States military carried out an airstrike on a site which it believed to have been occupied by Iranian-backed Iraqi militias operating from across the border in eastern Syria. The unilateral operation was in retaliation for multiple rocket attacks against U.S. forces in Iraq ten days prior and was the first known offensive military operation carried out under U.S. president Joe Biden.
