New Delhi, Apr 9 (IANS): Prime Minister Manmohan Singh Sunday offered Pakistan humanitarian assistance to help find survivors of a massive avalanche that hit a Pakistani army camp in the Siachen glacier in which 135 soldiers and civilians are feared dead.

During his talks with President Asif Ali Zardari, Manmohan Singh said he had heard the news about the avalanche. He added that if there was something humanitarian that was required of us, we would be happy to be of assistance, Foreign Secretary Ranjan Mathai told reporters.

Zardari thanked Manmohan Singh for his offer and said he would check and if there was any requirement, he would revert, Mathai said.

India's offer of assistance came even as the Pakistani military Sunday relaunched rescue efforts to find survivors in the Siachen glacier, the world's highest battlefield over which New Delhi and Islamabad have competing claims.

In a statement, the Pakistan military said that 135 people, including 124 soldiers, were missing from the camp after Saturday's tragedy.
