BASRA, Iraq (Reuters) - Three Katyusha rockets struck the outer perimeter of Basra’s airport on Saturday, local security sources said.

An official at the Iraqi airport said there was no disruption to operations, and flights were taking off and landing as normal.

No casualties or damage had been reported and it was not yet known who launched the attack, which came after five days of violent demonstrations that have damaged government buildings, political party offices and the Iranian consulate.
