KATMANDU, Nepal?Breaking weeks of tension, the foreign ministers of India and Pakistan shook hands and smiled on Wednesday, hinting that diplomatic talks could ease the crisis that has prompted a build-up of troops on their border.

The lighter mood was marred by violence in Kashmir, the Himalayan territory divided between the two nations. Suspected Islamic militants detonated two grenades near the legislature in Srinagar, the summer capital of the Indian ruled portion, killing one policeman and wounding at least 24 other people, police said.

In southern Kashmir, Indian and Pakistani forces traded fire across the disputed border. India said it killed at least five Pakistani soldiers and destroyed as many as 19 of their bunkers.

Pakistani police in recent days have arrested 50 members of the two militant groups blamed by India for a Dec. 13 attack on Parliament in New Delhi, officials from the groups said Wednesday.
