BAGHDAD: Iraqi authorities have arrested five suspects over a recent attack on a military base hosting US troops that wounded seven Americans, officials said Thursday. The rocket attack Monday was the latest in a series targeting Ain Assad base in recent weeks, which hosts American troops as well as other personnel from the US-led coalition against Daesh. The Iraqi government’s security media unit said in a statement that after “in-depth investigation and witness statements... five people involved in the illegal act were arrested.”
