ISLAMABAD Pro-Pakistani Kashmiri group has accepted the responsibility of an attack on an army camp in Indian-controlled Kashmir on Sunday, killing four soldiers and wounding 12 others, IRNA repo

"The Hizbul Mujahideen launched an operation `Azzm-e-Jihad' against the Indian Army, killing ten Indian troops and destroying two vehicles," a Hizb statement said.

The attack comes only five days after a major assault on another army camp in Indian-administered Kashmir, which left more than 30 people dead and triggered a new crisis in relations between India and

India accused Pakistani-backed militants of carrying out that attack and ordered the expulsion of the Pakistani high commissioner in retaliation.

Both countries have massed large numbers of troops along the Line of Control (LOC) in Kashmir, which in recent days has seen renewed heavy shelling.

Pakistan's Information Minister, Nisar Memon, said there were no plans to retaliate on the diplomatic front and Islamabad was hopeful the current crisis could be resolved peacefully.

Indian police said three militants stormed into the camp near Reasi in Udhampur district, some 150 kilometers (90 miles) north of Jammu, throwing grenades and firing indiscriminately.

Three soldiers and one paramilitary policeman died.

One of the militants was also killed, but the two others escaped.

"We will continue the guerrilla actions against the Indian Army till its last soldier would not leave the Jammu and Kashmir," the Hizb statement said.

On Sunday, Indian Prime Minister Atal Behari Vajpayee, who has been facing strong calls in Parliament to take action, met opposition leader Sonia Gandhi to discuss the Kashmir crisis.

No details of their discussions were disclosed, but the Congress Party leader has expressed full support for the Pakistani diplomat's expulsion.

Delhi has said the militants who carried out Tuesday's massacre had the backing of Pakistan, and has accused Islamabad of failing to carry out its pledge to clamp down on such groups.

But Pakistan says it has banned extremist Kashmiri groups and rounded up many of their members, alleging that those who carried out the attack in Jammu were indigenous fighters.

Correspondents say that exchanges of fire across the Kashmiri LOC are not rare but, given the current tensions, they have the potential to escalate into a wider conflict.

The two countries have deployed hundreds of thousands of troops along their shared border since a militant attack on the Indian Parliament in December.

India withdrew its high commissioner from Pakistan at the time and demanded the extradition of 20 `terrorists' and an end to what it calls `cross-border terrorism'.

The United States, the country with the most influence in the region, has sent several emissaries to try to lower tensions between the nuclear-armed rivals.
