A man wearing an Afghan police uniform shot and killed two soldiers with the NATO-led International Security Assistance Force in southern Afghanistan on Tuesday, ISAF spokeswoman Lt. Amy Hession told CNN.

No other details of the attack were immediately available.

Insider attacks by Afghan soldiers and police officers – or militants wearing uniforms – have been on the rise for months.

More than 50 people have been killed in Afghanistan in similar attacks this year. The Afghan government calls the killings acts of terrorism.

The so-called “green-on-blue” attacks have triggered concerns about the stability of Afghan security forces ahead of planned NATO withdrawals in 2014.

Update: The soldiers killed were British.
