Original Story:

Three soldiers, who were injured in Saturday’s terrorist attacks on the Pathankot Air Force Base in Punjab, India, later died in hospital, according to local news reports. Along with the four terrorists killed in Saturday's counterterrorism operations, the total number of dead now stands at 11.

Two more blasts and gunfire were heard from the base Sunday morning, leading to speculation that another terrorist could still be inside the base, according to the Hindustan Times, a local newspaper. The two blasts, triggered by improvised explosive devices, injured three soldiers and killed an officer, the newspaper reported.

Combing operations continued at the base throughout Saturday night, according to the Times of India, another local newspaper. Among the weapons and equipment recovered from the terrorists were AK-47s assault rifles, mortars, grenade launchers and GPS devices, the NDTV reported. The GPS devices would be analyzed to establish the route the terrorists took to enter the base, the report added.

Meanwhile, the investigation into Saturday’s attack has been handed over to India’s National Investigation Agency, whose officers reached the base around 11:30 a.m. local time on Sunday (1:00 a.m. EST), the Hindustan Times reported.

While authorities suspect the attack was carried out by Jaish-e-Mohammed, a terrorist group with its base in Pakistan, there has been no claim of responsibility for the terrorist attacks so far, Reuters reported.
