The most serious strike against the U.S. Navy since the USS Cole bombing in Yemen nearly five years ago killed a Jordanian soldier Friday, wounded another and sparked a nationwide manhunt for the culprits involved.

Two other rockets were fired toward Israel from the same warehouse, which is located in the hills on Aqaba's northern edge about 5 miles from the port. One fell short and hit the wall of a Jordanian military hospital and the other landed inside Israel close to Eilat airport, lightly wounding a taxi driver.

"We have found the rocket launcher in the warehouse from where they fired," Yirfas told The Associated Press in what marked one of the first key breakthroughs in the investigation.

"The investigation is still underway and issues related to it will remain secret so it would not harm the process," Yirfas said. "I cannot give you the names or say if we are looking for the perpetrators in the desert or any other place."

Jordanian security forces are hunting for six people, including one Syrian and several Egyptians and Iraqis, who are believed to have escaped in a vehicle with Kuwaiti license plates after firing the rockets.
