New Delhi: The Jammu and Kashmir police on Friday detained seven persons from Pulwama district in south Kashmir in connection with the deadly terror attack that claimed lives of 40 Central Reserve Police Force (CRPF) personnel near Awantipora.

Officials said that the youth were detained from Pulwama and Awantipora during the night on suspicion of links with the planning of the suicide attack, the first-of-its-kind in which a Jaish-e-Mohammed (JeM) terrorist detonated an explosive-laden vehicle near a CRPF bus.

Furthermore officials added, High-grade RDX explosive, weighing about 80 kilogram, was used in the suicide attack.  “A post-blast investigation conducted by security agencies has found that high-grade RDX” of about 80 kilogram was detonated in the blast,” officials stated.

Meanwhile, a National Investigation Agency (NIA) team, along with explosives and forensic experts, collected the materials required for a forensic evaluation of the scene of crime. Considering the status of the scene of crime, the team will continue with sifting of the material on Saturday as well. The outcome will be made known once the analysis is over.

Earlier in the day,  Union Home Minister Rajnath Singh had visited the Valley and paid tribute to the slain CRPF personnel. He also held a meeting with Governor Satya Pal Malik, the Chief Secretary, Director General of Police and officers of the Army and central security forces.

“I want to assure the people of Kashmir that the nefarious designs from across the border to sustain terrorism against India will not be allowed to succeed. I am happy that the people of Jammu and Kashmir are with us in the war against terrorism. I want to warn the people that there are some forces who would like to stoke communal passions. Whenever the county has faced such problems, people cutting across various sections of society and religious divide have stood together to defeat such designs,” Rajnath had said after the meeting.

On being asked if there had been a security failure vis-a-vis the terror strike, Singh said,”That is a matter of investigation and we will have to wait till the investigation into the terrorist strike is completed.”

Rajnath Singh earlier visited the Army Base Hospital in Srinagar where he met some of the injured jawans.
