The Army on Sunday said the four terrorists killed after they slaughtered 17 soldiers in Jammu and Kashmir were foreigners and belonged to Pakistan-based Jaish-e-Mohammed outfit.

The Director General Military Operations (DGMO), Lt. Gen. Ranbir Singh, told reporters here the army had recovered some articles with "Pakistan markings" from the slain terrorists.

"They were all foreigners and belonged to the Jaish-e-Mohammed," Gen Ranbir Singh said.

Jaish-e-Mohammed was also blamed for the January attack on an Indian Air Force base in Pathankot.

The DGMO said he spoke to his Pakistani counterpart and expressed concern over the Uri attack, one of the deadliest in Jammu and Kashmir in nearly three decades of insurgency.

Ranbir Singh said four AK-47 rifles and four under barrel grenade launchers and some other ammunition was recovered after the early morning attack.

He said 14 of the 17 deaths occurred due to a fire after militants hurled grenades at temporary structures.
