The U.S. has carried out an airstrike on a structure connected to an Iran-backed militia in Syria, following three separate rocket attacks against U.S. forces in Iraq, according to a defense official.

The strike, which was ordered by President Joe Biden, was designed to damage the militia group's ability to conduct future attacks, the official said.
