Police in Pakistani-controlled Kashmir say five girls have been killed by a cluster bomb.

Authorities say the young girls were playing with the toy-shaped explosive when it went off Friday in Kel village, near the line of control dividing Pakistani and Indian Kashmir.

Officials say such cluster bombs were used in large numbers by Indian forces along the line of control before a ceasefire three years ago. They say the Pakistani army has defused many bombs, grenades and toy-shaped bomblets, but that some are still lying in the farm fields.

Pakistan and India have a history of bitter relations and fought three wars over Kashmir.

Sporadic clashes and shelling along the border ceased following the ceasefire. Pakistan and India also have started a peace process to resolve the Kashmir conflict.
