A Jordanian military court has sentenced three Syrians and one Iraqi to death for firing rockets at two U.S. warships in the Red Sea port of Aqaba more than a year ago.
One of the Syrians is in police custody, but the other two and the Iraqi are at large and were tried in absentia.
Five others - three Iraqis and two Syrians - were given jail terms ranging from two to 10 years. Three Syrians were acquitted.
Several rockets were fired at the warships, USS Ashland and USS Kearsarge, in August 2005. The rockets missed the ships, but killed a Jordanian soldier.
The attack was described as one of the most serious assaults on American targets in Jordan in recent years.
U.S. diplomat Lawrence Foley was gunned down outside his home in Amman in 2002.
