On Monday, two Americans and a South African were gunned down by a Jordanian police officer at a police training complex in Amman, Jordan. The gunman was subsequently killed, too, in the related gunfire at the complex. Jordanian authorities said that all three of the training officers had been killed and had been working with Jordan’s public security department.

The Jordanian authorities also stated that the compound is used to train both Iraqis as well as Palestinians. In addition to the three murders, Jordanian authorities reported that two Americans and four Jordanians had also been hit and wounded in the gun battle, according to The New York Times. One of the four wounded men is listed as being in critical condition.

The two murdered Americans were not active military personnel but were independent contractors. According to the  latest reports, the dead Jordanian policeman who opened fire at the training complex had been recently fired from his job. The United States Department of State operates and funds the police training facility. It is there to teach Iraqi and Palestinian police officers.

The training center is staffed by Americans and British trainers as well as some others from other nations. Security forces linked with the Palestinian government have also received police training at the compound. Jordan continues to be an ally of the United States and is fighting in the American led coalition currently engaged in fighting the Islamic State in both Iraq and Syria. Jordan and Turkey are two of the countries that the Pentagon had sunk $500 million into training. The program was designed to create an opposition force in Syria capable of taking out the Islamic State forces.

The training program was discontinued and the pentagon decided to just supply and equip a coalition force instead. The suspicion for the attack may still rest with the Islamic State as it comes on the anniversary of another planned attack that killed 60 in a coordinated attack against three hotels in Amman a decade ago.
