Gunmen in Indian-occupied Kashmir raked a construction site work camp with bullets, killing seven people and wounding several others, Indian media reported on Monday, updating an earlier toll.
The attack on Sunday is one of the worst this year targeting civilians.
The contested territory’s chief minister, Omar Abdullah, called the attack late Sunday “dastardly and cowardly”, while India’s interior minister Amit Shah vowed those responsible would face the “harshest” response.
Muslim-majority Kashmir has been divided between rivals India and Pakistan since their independence from British rule in 1947, and is home to a long-running insurgency.
Attackers targeted workers from outside the Himalayan region, who were reported to be building a tunnel connecting Kashmir with the far northern Ladakh region.
Among the seven killed was a doctor, the Press Trust of India (PTI) news agency reported on Monday, adding several others were wounded.
