A Jordanian policeman opened fire Monday on foreign trainers at a police compound, killing two Americans and a South African before being shot dead, the government spokesman said.

Two Americans and four Jordanians were wounded in the shooting at the police training center on the outskirts of the Jordanian capital, Mohammed Momani told the state news agency Petra. He said one of the wounded is in critical condition.

Momani portrayed the shooting as a “crime” and said an investigation has been launched.

The U.S. Embassy had no immediate comment.

The shooting raises questions about Jordan’s image as an island of relative stability in a turbulent region. The pro-Western kingdom has taken on a high-profile role in the fight against Islamic extremists, including the Islamic State group, which holds large areas in countries bordering Jordan.
