Italian Helicopter Crash Kills Four

An Italian military helicopter has crashed in Iraq (search), killing the four people aboard, the Italian military said Tuesday.

The AB-412 helicopter (search) crashed overnight about eight miles southeast of Nasiriyah, the southern Iraqi city where Italy's 3,000 troops are based, the military said in a statement. The cause was not clear.

The helicopter was coming back from the Kuwaiti international airport and had stopped to refuel at Camp Buehring, also in Kuwait (search). Radio contact was lost soon after takeoff from the camp, the statement said.

A rescue team found the wreckage at dawn in the desert close to the Tallill air base in Iraq near Nasiriyah. The military said it was investigating.
