Two possible spots have been uncovered where four South Korean trekkers and three Nepalese nationals might have been when they went missing last week in the Himalayas.
The head of search and rescue operations in Nepal said on Monday that his team has detected signals from the equipment being carried by the missing.
He added there's a chance they could still be alive, but warned it's going to take at least two weeks perhaps even months for the snow to melt.
The missing South Koreans were part of a teachers' volunteer group working with children in Nepal.
They were on route to a Himalayan mountainwhen an avalanche struck last Friday.
