U.N. aid officials say the international response to the Pakistan earthquake must be intensified to provide relief for millions of survivors before the onslaught of winter.

The world body's humanitarian coordinator Jan Vandemoortele told reporters in Islamabad Saturday tents, emergency shelters and helicopters are the agency's top priorities.

Meanwhile, India has offered to set up three relief centers near the line of control separating Pakistani-controlled from Indian-controlled Kashmir.

The move follows a call by Pakistan earlier this week to allow Kashmiris to travel across the line of control to help relatives affected by the quake. Also this week, Indian officials opened direct telephone lines with Pakistani Kashmir for the first time in 15 years.

NATO agreed on Friday to send soldiers to the affected regions.

The powerful quake left more than 51,000 people dead and more than three million homeless.
