BAGHDAD -- Three Katyusha rockets landed in the perimeter of Baghdad International Airport on Wednesday, the Iraqi military said.

The military said it found a rocket launcher with a timer in a rural area in western Baghdad, and there were no reported damages or casualties.

There was no immediate claim of responsibility.

The rockets were fired from the Bakriya neighborhood, about 6 km (4 miles) northeast of the airport, and security forces were deployed to search the area, security sources said.

Security officials said it was not immediately clear whether a military base which hosts US troops near the airport was the target of the attacks.

Iran-backed paramilitary groups have regularly been rocketing and shelling bases in Iraq that host US forces and the area around the US Embassy in Baghdad. -- Agencies
