Fourteen people, including two security personnel, were injured on Sunday in a grenade explosion triggered by militants in Anantnag district of Jammu and Kashmir.

The grenade, aimed at an army convoy, missed the target and exploded on the road at Bijbehara, 40 kms from Anantnag, injuring 12 civilians, one policeman and a personnel of Indo-Tibetan Border Police, official sources said.

The ITBP personnel and three others were seriously injured in the blast and admitted to a hospital in Srinagar.

This was the second attack on an army convoy in the state in 24 hours.

On Saturday militants had triggered a landmine blast at Pampore on Srinagar-Jammu national highway, which smashed windowpanes of two vehicles of an army convoy and a milk van but did not cause any casualty.

Security forces searched the area in the town. No one has yet claimed responsibility for the blast.

Meanwhile four militants were killed in a fierce gun battle in the northern border district of Kupwara this morning during a search operation. One more militant was killed near Handwara in the same district.
