One British civilian was hurt in the attack, but there are no details of the injuries.
The three people killed were not Britons, and the nationality of a second injured person was unknown.
Meanwhile, the British military said two British civilians had been hurt on Saturday in a bomb blast near Basra, in southern Iraq.
The pair were part of a contractor convoy that was struck by a roadside bomb 40km northwest of the city.
The injured Britons were taken by helicopter to the British military base in Shaibah, south of Basra.
