Authorities say three Indian soldiers and their two civilian porters have been killed in a rebel ambush in Indian-controlled Kashmir

Indian police say that gunmen killed at least seven people working on a strategic tunnel project in Indian-controlled Kashmir and injured at least five others.

At least four people, including two soldiers, were killed when militants ambushed an army vehicle in India's restive Kashmir on Thursday night, officials said, the fourth attack in the region in a fortnight and the second this week.

Gunmen killed at least seven workers, and injured five others, at a key tunnel project in Jammu and Kashmir on Sunday, according to the police, making it one of the worst attacks on an infrastructure project in the volatile Indian region.

Kashmir has been divided between India and Pakistan since their independence from British rule in 1947. India's army confirmed an "exchange of fire" had taken place with "terrorists," saying the incident occurred late on Thursday in the vicinity of Gulmarg,
