- Gunmen fire automatic weapons at camp from forested hills around.

Gunmen in Indian Illegally Occupied Kashmir (IIOJK) raked a construction site work camp with bullets, killing seven people and wounding several others, Indian media reported Monday.
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.
Attackers targeted workers from outside the Himalayan region, who were reported to be building a tunnel connecting IIOJK with the far northern Ladakh region, AFP reported.
Among the seven killed was a doctor, the Press Trust of India (PTI) news agency reported on Monday, adding several others were wounded.
Abdullah, who was sworn in as the region's chief minister on Wednesday after its first local elections for a decade, said he strongly condemned the attack on "non-local labourers".
Soon after the attack, Abdullah confirmed two people had been killed but had warned there were also "a number of injured labourers, both local and non-local".
Shah called the killings "a despicable act of cowardice", in a statement.
"Those involved in this heinous act will not be spared, and will face the harshest response from our security forces," Shah said.
The attack took place Gagangir in Sonamarg region, where Nitin Gadkari, India's minister of roads said the "innocent labourers" had been working on a "vital infrastructure project".
Gunmen fired automatic weapons at the camp from forested hills around, Indian newspapers reported.
Nine Indian Hindu pilgrims were killed and dozens more wounded in June when a gunman opened fire on a bus carrying them from a shrine in Reasi district.
