Freezing temperatures and a winter storm that began dumping heavy rain and snow over the weekend have claimed the lives of at least 52 people in Jammu-Kashmir state, witnesses and officials said Tuesday.

It was still snowing Tuesday in Kashmir Valley, where authorities said at least 20 people had died since Monday in avalanches and the collapse of roofs under heavy snow.The state's summer capital, Srinagar, was blacked out for a fourth straight day Tuesday after electricity poles with snow-laden cables crashed down.

The stormy weather apparently curtailed militant activity in the Kashmir Valley, where about five people are killed on an average every day in an ongoing separatist insurgency by Muslim militants.
