Kathmandu, May 7 : Three people were killed and 12 others wounded in another avalanche in Mugu district in northwestern Nepal, a local official said on Sunday.

The injured were received treatment at a local health post, he said.

A team of security personnel was sent for the rescue operation, but was hindered by snowfall, said Mohan Bahadur Thapa, chief district officer of Mugu, which is known as the most remote district in Nepal.

"The incident site is about a two-day walk from the district headquarters. Our rescue team hasn't reached there yet," he told Xinhua.
