India stepped up security on its border with Pakistan on July 27 after gunmen attacked a police station in northern Indian state of Punjab, killing at least five people.
Officials said on July 27 that Indian army commandos and police clashed with the heavily armed attackers who stormed into police barracks in Gurdaspur district, near the Pakistani border.
Police said they were combing the area after the siege that lasted nearly 12 hours. All the gunmen involved in the attack were dead, police said.
Authorities said the attackers, believed to have come from the Indian portion of Kashmir, hijacked a car and then fired at a bus station before entering the police station.
New Delhi Television news channel said three to four rebels carried out the attack.
Several bombs have been found on railway tracks near the police station, local media reported.
Senior police officer Dinkar Gupta said army and police reinforcements poured into the area and were exchanging gunfire with the rebels holed up in the barracks.
Home Minister Rajnath Singh said he has "instructed" the head of India's Border Security Force "to step up the vigil on India-Pakistan border."
