Srinagar, May 5: Three militants, three civilians and a policeman were killed in fresh violence in the Kashmir Valley on Saturday as authorities imposed strict restrictions and snapped mobile phone Internet services following protests near a gunfight site in an old Srinagar neighbourhood. Police said three Lashkar-e-Taiba (LeT) militants were killed and four security personnel injured in the shootout in Chattabal, few kilometers away from city centre of Lal Chowk. The gunfight triggered stone-pelting protests by local residents, who tried to help the holed-up militants escape from a hideout in a semi-constructed building in the densely populated locality of downtown Srinagar.
