Bomb blast as India debates

Members of one of India's political parties protest near the Pakistani embassy in New Delhi

JAMMU, India (CNN) -- A blast ripped through the capital of Kashmir as India's parliament debated how to respond to a deadly attack in the disputed region earlier this week.

At least two people were killed in the blast at the fire services headquarters in Srinigar on Friday, which also injured 16 people. Nobody has claimed responsibility for the blast.

The explosion followed some of heaviest fighting in months across the line of control in Jammu-Kashmir between Indian and Pakistani forces.

The escalation in tensions come as India debates what action it will take after more than 30 people were killed and 40 wounded in a raid on an Indian army camp in Kashmir on Tuesday this week.

India has blamed Pakistan for the deadliest attack in eight months on its side of the disputed region of Kashmir.

Pakistani police arrested the leader of the group India blames for Tuesday's attack, but New Delhi says Islamabad hasn't done enough to stop the violence.

Several lawmakers have called for military action against Pakistan following the attack.

Pakistan has condemned the attack but said it was prepared for any military response from India.

The nuclear neighbors have fought two of their three wars over Kashmir, and have masses of troops on war alert along their frontier following a December raid on India's parliament, blamed on Pakistani-based militants.

Cross-border exchange on Friday included arms and mortar fire.

At least four people were injured in the fighting, which has spurred the flight of hundreds of families in frontline villages.

The Indian parliament in New Delhi is debating a strategy to combat "increasing terrorism from Pakistan" as it comes under growing pressure to take military action.

In parliament Friday, several speakers asked the government not to rely on the international community to fight terrorism.

Parliamentarians say India should form its own strategy to fight terror and also get tough with Pakistan.

Response due

India's response is due later Friday or early Saturday morning.

More than a dozen Islamic groups have been fighting for Kashmir's independence from India since the militant insurgency began in 1989.

Authorities say that around 30,000 people have been killed during the campaign in the Muslim majority state.

India accuses Islamabad of arming and training Pakistan-based militant groups but Pakistan denies the charges, saying instead it only provides moral and diplomatic support for Kashmiri separatists.

India controls about 45 percent of Muslim-majority Kashmir, Pakistan a third and China the rest.
