Iraq said Wednesday that two people were killed and 13 injured when U.S. and British warplanes bombed what it called civilian installations in the south of the country.

In a statement published in state-run newspapers, an unidentified military spokesman said the strike took place Monday night, but he gave no details of the targets.

On Tuesday, the U.S. military said American warplanes bombed two Iraqi anti-aircraft radars that threatened pilots patrolling the southern no-fly zone.

The planes used precision-guided weapons to target the mobile radar equipment near Al Amarah, about 165 miles southeast of Baghdad, according to a statement from U.S. Central Command. The airstrike took place at about 3:30 p.m. EST Monday, the statement added.

It was the second airstrike this year by American planes patrolling the southern no-fly zone, which was set up more than a decade ago to prevent Iraq's army from attacking restive Shiite Muslims in the region. A strike on Saturday targeted three Iraqi air defense communications sites in the same general area as Monday's strike.

U.S. and British warplanes patrol another no-fly zone in northern Iraq to protect the Kurdish minority. Iraq considers the no-fly zones violations of its sovereignty and frequently tries to shoot down the planes.
