PATHANKOT, India — Suspected militants infiltrated an Indian air force base near the border with Pakistan and fought security forces for hours, leaving at least four gunmen and two Indian troops dead in what is being seen as a possible attempt to undo recent progress in relations between the two rival countries.
The attack Saturday at the Pathankot air force base in Punjab came just a week after the first visit to Pakistan in 12 years by an Indian prime minister. Police said they were investigating whether the gunmen came from the Indian portion of Kashmir, where rebels routinely stage attacks, or from Pakistan.
The assault began a couple of hours before dawn when a group of gunmen entered the section of the base where the living quarters are, the Defense Ministry said. The attackers, however, were unable to penetrate the area where fighter helicopters and other military equipment is kept, it said.
By late morning it appeared that the violence had ended with the killing of the gunmen by Indian forces. But two hours later, more gunfire erupted and an air force helicopter was seen firing at an area of the base, a major installation about 267 miles north of New Delhi.
Air force spokeswoman Rochelle D’Silva said Saturday night that troops were combing the entire base to fully secure it. She said that operation was expected to continue through the night.
The full number of casualties would be clear once the base was completely secured, she said.
By 9 p.m., no gunfire had been heard around the base for more than three hours.
Indian Prime Minister Narendra Modi made an unannounced visit to Pakistan Dec. 25 to meet with his Pakistani counterpart, Nawaz Sharif. The visit was seen as a potential sign of thawing relations between the two nuclear-armed neighbors. The two leaders also held an unscheduled meeting at the Paris climate change talks last month.
The Indian Defense Ministry said there had been intelligence reports about a likely terror attack on military installations in Pathankot, and that the air force had been prepared to thwart any attackers.
“Due to the effective preparation and coordinated efforts by all the security agencies, a group of terrorists were detected by the aerial surveillance platforms as soon as they entered the Air Force Station at Pathankot,” the ministry said in a statement.
Despite the intelligence on a possible attack, at least two air force troops were killed in the gunbattle, the Press Trust of India news agency reported. PTI, citing police, also said at least four gunmen had been killed.
Pathankot is on the highway that connects India’s insurgency-wracked Jammu and Kashmir state with the rest of the country. It’s also very close to India’s border with Pakistan. The Himalayan region of Kashmir, where rebels have been fighting since 1989 for independence or merger with Pakistan, is divided between India and Pakistan, but is claimed in its entirety by both.
India accuses Pakistan of arming and training Kashmir’s insurgents, a charge Pakistan denies, and the attack was viewed by many in India as an attempt to unravel recent progress in the relationship between the two countries.
Modi, at a speech in the southern city of Mysore, congratulated security forces “for turning the intentions of our country’s enemies into dust. They didn’t let them succeed. And I salute the martyrdom of the soldiers who sacrificed their lives.”
Indian Home Minister Rajnath Singh told reporters that India wants peace with Pakistan, but “if there is any kind of terror attack on India, we will give it a fitting reply.”
Pakistan’s Foreign Ministry condemned the attack.
