A Jordanian policeman killed two Americans and a South African during an attack on a police compound in Amman, Jordan, on Monday. Two Jordanian's were also killed.

The attacker, who is now dead, opened fire on the foreign trainers at King Abdullah police training facility in Muwuaqqar, on the outskirts of the city.

Mohammed Momani told the state news agency Petra that two Americans and four Jordanians were wounded in Monday's shooting at the training center on the outskirts of the Jordanian capital, adding that one of the wounded is in critical condition.

The attack also wounded seven people, including two Americans, three Jordanians and a Lebanese, Momani said.

Momani portrayed the shooting as a crime and said an investigation into the attack is underway. Little information has been confirmed about the attacker, but local media is reporting that he is a 29-year-old police captain.
