Seven rockets were found in an agricultural field near Kangarh chowki (post) in Attari sector early on Saturday, Jan 9.
The rocket blasts and firing took place between 2 am and 3 am. However, there were no casualties reported.
While five rockets landed near a village, two rockets landed near the BSF post, Punjab frontier Inspector General of Police (IGP) Himmat Sing informed.
"Our troopers fired back. Senior officers have already reached the spot and investigations are on. We had a meeting with our Pakistani counterparts and have lodged a strong official protest," Singh said.
This is the third incident of rockets being fired from across the border. The last two incidents at the Pul Kanjari area of the international border took place in Jul 2009 and Sep 2009.
The incident took place almost during the same time as the heavy firing in Jammu Kashmir along the Indo-Pak international border.
Two days ago, militants, believed to be members of the Lashkar-e-Toiba, carried out a 22-hour long attack in Srinagar's Lal Chowk area.
All these incidents have raised doubts if all this is a diversion to infiltration.
