Srinagar, Aug 1 - A Central Reserve Police Force (CRPF) trooper was killed and another injured as separatist guerrillas opened fire at the high-security Regal Chowk area here Saturday morning, police said.

The militants fired from a point blank range in the busy market place, half a kilometre from city centre Lal Chowk. As soon as the gunfire was heard, shoppers and passersby ran for cover.

The area has been cordoned off and a search for the militants is on.
