Pakistan summoned India's deputy high commissioner on Thursday to condemn what it called "unprovoked" firing over the disputed Kashmir frontier that violated a 2003 ceasefire and killed one civilian, the foreign ministry said.

Deputy High Commissioner J P Singh met with Pakistani officials to discuss the firing on Wednesday and Thursday, which also wounded two others in Azad Jammu Kashmir, according to a statement from the Foreign Office.

"The deliberate targeting of civilians is indeed condemnable and contrary to human dignity and international human rights and humanitarian laws," the statement read.

Pakistan and India have faced off for decades across the Line of Control separating parts of Kashmir held by both countries. The old ceasefire line runs through a region that both countries claim in full but rule in part.

Sporadic cross-border attacks in past months have frayed the 2003 truce.

Last week, India accused Pakistani forces of killing two soldiers patrolling the Line of Control and mutilating their bodies. Pakistan's military denied the allegations and said it had not committed ceasefire violations.
