Aqaba, Jordan ? Police detained several suspects on Saturday as the hunt widened for the attackers who fired and supplied the rockets that narrowly missed a U.S. Navy ship anchored in the bay of this Red Sea port best known for beach vacations and Mideast summits.

Those arrested included Iraqis, Syrians, Egyptians and Jordanians, according to a Jordanian security official, who spoke on condition of anonymity because he was not authorized to comment. He would not give the number of detainees.

Interior Minister Awni Yirfas told The Associated Press that security forces had found the launcher used to fire the three Katyusha rockets.

Police found four more rockets when they seized the launcher in a warehouse in an industrial zone on a hillside overlooking Aqaba, state TV reported Saturday. The four rockets were defused, the report said.

Authorities said the warehouse used to launch the notoriously inaccurate rockets had been rented days beforehand by four men carrying Iraqi and Egyptian identity papers.

The security official who disclosed Saturday’s arrests said an Iraqi detainee was suspected of taking part in the attack, but he cautioned against assuming the others arrested were equally involved.
