SRINAGAR, India (AP) _ Separatist militants fired six rocket-propelled grenades at the main government building in Kashmir's capital Thursday, killing three people and injuring 28 others, police and witnesses said.

The explosions shattered windows and damaged the outer walls of the building, which houses offices of top Indian government officials, including the state's chief minister.

Panicked employees rushed out of the seven-story building in Srinagar.

Two employees of the state education department died in the attack. A soldier died later at a local hospital, police said.

Militants fighting for an independent Kashmir or for a merger with neighboring Pakistan have stepped up attacks since this summer, when India evicted hundreds of Pakistan-backed fighters from strategic peaks they had occupied in northern Kashmir.

The attack came an hour after suspected militants threw a grenade at a border police post in downtown Srinagar, just 500 yards from the secretariat. Four security force personnel were injured in the attack.
