Of the 11 civilians killed so far, nearly half came to J&K from other states, including Bihar

New Delhi: The National Investigation Agency - India's counter-terrorism force - will probe the targeted killing of four civilians in Jammu and Kashmir this month, sources said Tuesday morning. The NIA has been mandated by the Union Home Ministry to investigate the larger conspiracy behind the killings.

Sources said the agency is expected to take over inquiries into the killing of Makhan Lal Bindroo, Virender Paswan, Supunder Kaur and Deepak Chand, as well as that of two labourers from Bihar.

The two Bihar labourers - Raja Rishidev and Yogendra Rishidev - were the most recent reported deaths - they were shot dead by terrorists in Wanpoh in Kulgam district on Sunday.

Their deaths came a day after a golgappa seller, also from Bihar, and a carpenter from Uttar Pradesh were shot dead in the Valley. The golgappa seller, Arbind Kumar Sah, was shot at from point-blank range in Srinagar and the carpenter, Sagir Ahmad, was killed in Pulwama, police said.

Other victims have included 70-year-old ML Bindroo, a prominent member of the Kashmiri Pandit community and the owner of a pharmacy in Srinagar, who was one of three people killed October 5 - when this wave of attacks started.

The others killed on the day were Mohammad Shafi Lone, a taxi driver in Bandipore district, and Virender Paswan, a street food vendor who also came to J&K from Bihar.

Two days later, on October 7, two teachers at a government school in Srinagar were shot dead - Supunder Kaur and Deepak Chand. They were from Kashmir's minority Sikh and Hindu communities.

Of those killed so far, five are from other states and there appears to be no particular community that has been targeted; Hindus, Muslims and Sikhs are among those killed.

Either way, the killings have sparked fear in the Valley, prompting an exodus of Kashmiri Pandit families from transit camps. Dozens of families, including those of government employees who returned after getting jobs under the Prime Minister's special scheme, have left.

Migrant labourers and workers from other states have also begun leaving J&K; the neighbour of one of those killed said he was leaving because he was scared for his family's safety.

Security forces have launched a massive crackdown and have detained about 900 people for alleged links to separatist outfits like the banned Jamaat-e-Islami. Police have also attributed some attacks to 'The Resistance Front" - believed to an offshoot of the banned Lashkar-e-Taiba.

Anti-terror operations have also been intensified, with two terrorists, including a Lashkar commander, killed in Pulwama district on Saturday. The day before, police said two terrorists allegedly involved in the killing of two civilians and a cop were killed in back-to-back encounters.

The spate of attacks has come at a time when the army is engaged in one of its longest and toughest anti-terrorist operations in the Poonch district; nine Indian soldiers have been killed in such fierce fighting that Army and police sources suspect they may have been trained by Pakistani commandos.
