A powerful hand grenade explosion rocked Srinagar [Images] on Wednesday evening. According to the police, militants tossed a grenade at a bunker of the paramilitary central reserve police force in the Kawdara area of the old city late today evening.

"The grenade exploded on the road, after missing the target and injured two civilians, who were taken to hospital for treatment," a senior police officer said.

The area was surrounded and searched by the Central Reserve Police Force.

Another powerful hand grenade was lobbed at the residence of the station house officer of Kangan in north Kashmir's Ganderbal district today evening.

However, no one was injured in the explosion, which took place on the route of the annual Amarnath yatra. The police said that the grenade exploded near the compound wall of the house without causing any damage.

Today's blast in Srinagar comes after a prolonged lull in militant violence.
