Rockets fired at U.S. warship

Jordanian police are using helicopters and roadblocks to track down four people suspected of firing three rockets today from a warehouse.

A group linked to al-Qaida is claiming responsibility for the rocket attacks -- one of which barely missed a U-S Navy ship. But the statement hasn't been verified.

Officials say two American amphibious ships were docked today in the Jordanian port of Aqaba when a rocket was fired toward them. Both ships have left the port.

It was the most serious militant attack on the Navy since the USS Cole was bombed in 2000.

A Jordan news agency says the rockets were fired from a warehouse in Aqaba. It was rented to four people holding Egyptian and Iraqi nationalities.
