Srinagar, Aug 31 - Five Central Reserve Police Force (CRPF) troopers were injured Monday after separatist guerrillas struck in two separate localities of this Jammu and Kashmir summer capital.

The guerrillas hurled a grenade at a CRPF bunker in Batmaloo area, barely 150 metres from the high-security Civil Secretariat, leaving injured seven people - four civilians and three para-military troopers.

Minutes before this attack, guerrillas fired from point blank range at two CRPF troopers in Lal Chowk and injured them critically. 'Both jawans were shot in the head and were evacuated to hospital for treatment,' a senior police officer said.

The condition of the two CRPF troopers is stated to be critical, according to hospital sources here.

The shootouts have triggered high tension in the areas which were surrounded by security forces.

No group has yet claimed responsibility for the attacks.

Early this month, two security men were shot and killed by guerrillas in two separate incidents in the capital city.
