Warplanes from India launched an attack on an alleged militant camp Tuesday morning, violating Pakistani airspace in the disputed territory of Kashmir in the latest escalation between the two nuclear powers. The attack carried with it fears of wider war between the two countries. 

“Armed conflicts once started take their own course without either side being in control to decide where such hostilities will end,” Professor Muzaffar Ahmed told Indian news service IANS.

The aerial attack came in the wake of heightened tensions between India and Pakistan, after a Feb. 14 suicide attack on Indian security forces in the Kashmiri town of Pulwama, which killed 42, led to India cutting Pakistan off from a key water source controlled by the former on Feb. 21.

The result of the morning’s Indian incursion was unclear at press time. Indian foreign secretary Vijay Gokhale claimed the attack struck a militant training camp and blamed the Pakistani government for allowing the camp to flourish. “The existence of such training facilities, capable of training hundreds of jihadis,” said Gokhale, “could not have functioned without the knowledge of the Pakistani authorities.”

Pakistani sources disagreed with the Indian version of events and said the Indian planes had dropped their payload without a target, showing craters near the small town of Balakot as evidence.
