Jordanian authorities have arrested an Iraqi man suspected of taking part in rocket attacks at the Red Sea port of Aqaba.
Officials said Saturday's arrest came as police seized four more rockets in a warehouse near the port.
Officials say they are still looking for an Iraqi and four Egyptians who rented the warehouse days ahead of Friday's attack.
One rocket in the attack flew over an American naval ship at the port and struck a Jordanian military warehouse, killing one soldier. Another exploded near a military hospital, and a third landed on Israel's side of the border.
A group linked to al-Qaida has claimed responsibility for the attack.
