A detailed article by Shashank Joshi (RUSI) via the Australian Lowy Institute's email briefing:
On 27 July, three (Kashmiri) militants crossed from Pakistan into the Indian state of Punjab, according to GPS sets they were carrying. They planted five IEDs on a railway track, targeted bus passengers and holed up in a police station in Gurdaspur 20km from the border, eventually killing seven Indians. The attackers were themselves killed by local police after a day's siege.
