Search teams aided by Pakistani troops pulled out 21 more bodies from homes destroyed by this week’s avalanches in the disputed Himalayan region of Kashmir, raising the overall death toll due to severe winter weather to 160 for Pakistan and Afghanistan, officials said Wednesday.

Rescuers were racing against time to reach scores of people believed still to be trapped inside their homes, buried under avalanches triggered by heavy snowfall in Pakistan-administered Kashmir. With many roads still blocked by snow, authorities were using helicopters to evacuate those injured.
