Bagh, Pakistan ? Subfreezing temperatures and the first snowfall in Kashmir claimed the life of an infant Monday – the first reported victim of what officials fear will be a new disaster for millions of Pakistanis left homeless by an earthquake.

A middle-aged man with terminal cancer also died after he was taken to a NATO hospital suffering from hypothermia.

“This is exactly what we had feared. Our position here is we need to continue to do as much as possible to help mitigate this situation and prevent, insofar as that’s possible, any such occurences in the future,” said Stephanie Bunker of the U.N. Office for the Coordination of Humanitarian Affairs.

Another United Nations official, Elisabeth Byrs, said the relief effort remains underfunded and that, according to the Pakistani military, at least 300,000 people remain inaccessible in remote Himalayan regions. None have tents, she said.

Troops and aid workers are building shelters as fast as they can. But with heavy rains and a fresh blanket of snow over the last two days heralding the onset of the region’s harsh winter, it is not fast enough for those who have been living rough since the Oct. 8 earthquake that killed more than 87,000 people.

The middle-aged man died at a NATO hospital early Monday, a day after he was brought in with hypothermia, said Lt. Col. Johan De Graaf, the facility’s senior medical officer.

Three-month-old Waqar Mukhtar died of pneumonia hours after he was brought to a hospital in Muzaffarabad, said Dr. Abdul Hamid.
