Helicopters were sent out on Saturday to rescue about 200 people stranded around Annapurna and other nearby mountains after the incident.
An avalanche in Nepal's Annapurna region has left at least seven people missing, including four South Koreans and three Nepalis, officials said on Saturday (Jan 18).
The missing group was near the Annapurna base camp around 3,230 metres (10,600 feet) above sea level when the avalanche struck after heavy snowfall on Friday.
The search and rescue mission for the missing climbers has been called off after experts feared the area had become too risky, the Department of Tourism official Meera Acharya said.More news: South Africans with slow access to global websites - SAPeople
Local police chief Dan Bahadur Karki said poor weather was hampering rescue efforts.
Photos from the area shared on social media showed guesthouses along the trekking route blanketed in a thick layer of white.
The four foreigners were part of an 11-member team of South Korean nationals.
The missing trekkers - two women in their 30s and 50s and two men in their 50s - were teachers who were staying in Nepal for volunteer work, the ministry said, according to the Yonhap news agency.More news: Snow emergency declared for City of Milwaukee
A second search mission is being planned for the missing South Koreans and local guides but it would have to wait for snow and ice to stop falling before the operation resumes. Others from the team are safe. "As they were heading back they were hit by an avalanche", Sherpa said.
Thousands of trekkers visit the Annapurna region every year for its stunning views of the Himalayas.
The incident comes as the annual trekking season in Nepal, home to eight of the world's 14 highest mountain peaks including Mount Everest, is drawing to a close.
The Friday avalanche hit along the popular Mount Annapurna circuit trekking route following rains and snow earlier in the week.More news: Selena Gomez surprises fans with 'rare' music video hours after album release
