This photo provided by Azim Afif shows the scene after an avalanche triggered by a massive earthquake swept across Everest Base Camp, Nepal on Saturday, April 25, 2015. Afif and his team of four others from the Universiti Teknologi Malaysia (UTM) all survived the avalanche.

Up to 250 people are missing in Nepal after an avalanche hit a village in Rasuwa district, a popular trekking area to the north of the capital Kathmandu, District Governor Uddhav Bhattarai said on Tuesday.

Foreign tourists may be among the missing in the avalanche, which hit the village of Ghodatabela. A powerful earthquake last Saturday with a magnitude of 7.9 set off many snowslides in the Himalayan state.
