Jordanian police officer goes on gun rampage killing two Americans

Two Americans have been shot dead by a Jordanian police officer who then killed himself.

They were gunned down at a U.S.-funded facility for training Iraqi and Palestinian security forces in Jordan.

The officer went on a shooting spree at the facility in Muaqar on the easte outskirts of the capital Amman, said the source, who requested anonymity.

Another security source said there were unconfirmed reports that at least three other U.S. service personnel were injured.

Jordan is a staunch U.S. ally and part of the Washington-led coalition that is trying to defeat Islamic State in Syria and Iraq, both of which border Jordan.

The country hosts several hundred U.S. trainers who are part of a military programme to bolster the kingdom"s defences, including the stationing of F16 fighter jets that use Jordanian airfields to hit Islamic State positions in Syria.

But the kingdom"s role in the war against Islamic State has caused disquiet among some Jordanians worried about instability at their borders and fearing that a stepped-up role in the campaign might lead to Islamist attacks in their country.

King Abdullah believes fervently that ultra hardline jihadists pose an existentialist threat to the kingdom.
