Two Americans shot dead by Jordan police officer at training camp
At least two others injured in shooting spree on outskirts of Amman
A Jordanian police officer shot and killed two Americans at a US-funded facility for training Iraqi and Palestinian security forces before committing suicide.
The Jordanian went on a shooting spree at the facility in Muaqar on the eastern outskirts of the capital Amman, said a security source.
Another source speaking to Reuters said there were unconfirmed reports that at least three other US service personnel were injured.
The facility is a regional centre used by the US to train security forces including Palestinians and Iraqis.
The shooting occurred on the 10th anniversary of a series of three coordinated attacks targeting three hotels in Amman undertaken by al-Qaida in Iraq.
Jordan is a staunch US 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 US 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.
