A strike near Iraq's western border with Syria killed three fighters from former coalition Hashed al-Shaabi on Wednesday, the alliance said.
The fighters from the alliance -- also known as the Popular Mobilisation Forces (PMF), now part of Iraq's regular armed forces -- were hit in an US or Israeli strike that targeted their main command centre in Anbar province, AFP reported.
Since the start of the Middle East war, Baghdad has repeatedly denounced attacks on the Hashed al-Shaabi, which also includes brigades belonging to Iran-backed groups.
