Pakistan Foreign Secretary Aizaz Ahmad Chaudhry summoned Raghavan to convey that today's ceasefire violations by the Indian side were not acceptable, sources said.
Chaudhry handed over the protest note to Raghavan, who was accompanied by his deputy J P Singh.
"While condemning the Indian practice of targeting civilians on purpose, Pakistan expressed its deep concern at the continued hostility at the LoC and the Working Boundary," the Foreign Office (FO) said in a statement.
"Pakistani troops initially exercised restraint however, responded befittingly when India started heavy firing. The firing ended today at 1100 hours.
"The Indian Government was urged to stop forthwith the ceasefire violations and observe the 2003 Ceasefire Arrangement for restoration of peace and tranquility at the LoC and the Working Boundary," it said.
This comes less than a week after Pakistan called off the first-ever NSA-level talks between the two countries amid acrimony.
