Indian troops fired mortars across the disputed border in Kashmir on Friday, killing a child and wounding three other people, Pakistani officials said.

The incident took place in Nakyal sector, along the Line of Control (LoC), the heavily militarised de facto border between Pakistan and India, in the disputed Himalayan region of Kashmir.

"An 11-year-old boy was killed and three others including two women were wounded in the Indian shelling," in senior local administration official Masood-ur-Rehman told AFP.

A senior police official in the area, Muhammad Amin, confirmed the incident and casualties.

The latest incident came almost two weeks after the prime ministers of the two countries pledged to restore calm on their disputed border in Kashmir, at a meeting in New York.

A deadly flare-up along the LoC in January brought a halt to peace talks that had only just resumed following a three-year hiatus sparked by the 2008 attacks in Mumbai that killed 166 people.

Fresh skirmishes erupted on the LoC after five Indian soldiers were killed in a raid in August.

Delhi blamed that ambush on the Pakistan army, but Islamabad denied the claims and has repeatedly called for restraint and dialogue.

Kashmir, a Muslim-majority territory, is divided into Indian and Pakistani-administered sectors but is claimed in full by both sides.
