Two Americans among the dead after shooting at police training center in Jordan

Two U.S. State Department contractors were killed after a Jordanian policeman opened fire Monday at a police training center, a U.S. official and a Jordanian government spokesman tell Fox News.

The shooter also killed two Jordanians and a South African, according to the Jordanian embassy in Washington. Police shot and killed the gunman, who was dressed in a military uniform.

Two additional U.S. trainers and at least two other Jordanians were reported hurt, and are receiving treatment in Amman.

DynCorp International, a Virginia-based company that provides security, aircraft and intelligence worldwide, confirmed some of its personnel were shot, but did not identify them. "The company extends its thoughts and prayers to all involved and to their families and loved ones," DynCorp said in a statement.

The shooting came 10 years to the day after a string of bombings killed a total of 60 people at three hotels in Amman. It's not clear whether Monday's attack was related, but it cast a troubling light on Jordan's image as an island of relative stability in a turbulent region.
