Two suspected insurgents hurled hand grenades and fired on Wednesday at a group of government forces in a crowded shopping district in Srinagar city, killing at least one police officer and wounding three civilians, police said. The attackers later took shelter in a nearby building and were exchanging gunfire with Indian security forces, said Farooq Ahmed, an inspector-general of police. Panicked shoppers fled as armored vehicles carrying police reinforcements arrived in the central Lal Chowk district of Srinagar, Ahmed was quoted as saying by the Associated Press. The injured civilians included a cameraman from a television news channel, said Sajad Ahmed, another police officer. The civilians were hospitalized with bullet and shrapnel wounds, he said.
