The National Investigation Agency on Tuesday filed an FIR in connection with Sunday's attack at the Indian Army base in Jammu and Kashmir's Uri. Six NIA officials will visit the site to collect blood samples and fingerprints of the four militants who were gunned down during the strike at the Army installation, PTI reported.

The Army will hand over the weapons, Global Positioning System devices, maps used by the militants and other evidence they recovered from the location to the agency for further investigation, ANI reported. The NIA will, in turn, send the GPS devices to the United States for forensic analysis to ascertain details such as the route the militants used to infiltrate the camp as well as how and when they entered the Uri base in Baramulla district.

Meanwhile, authorities have lifted the curfew from across Kashmir, except for areas under the jurisdiction of the six police stations in Srinagar. Restrictions were imposed on Sunday as separatist organisations had called for a march to the districts of Bandipora, Ganderbal and Shopian. However, a police officer told PTI that Section 144, which prohibits the assembly of 10 or more people at a location, continues to remain in force in the state.

Normal life has yet to return to the Kashmir Valley as it entered the 74th day of unrest on Tuesday. So far, at least 85 civilians have died and thousands have been injured in clashes with security forces. Shops, schools, colleges and business establishments remained shut, and public transport was also off the roads, as the separatist-sponsored strike was extended till September 22. Outgoing calls from prepaid mobile numbers and mobile internet services continue to be suspended, while postpaid connections were restored on Monday night.
