At least 24 trekkers died Tuesday after being caught in an avalanche and heavy snowfall triggered by India's cyclone Hudhud in Nepal's northern Himalayan districts.

Fourteen trekkers died in the district of Mustang and another eight in Manang about 400 km north-west of Kathmandu.

"The trekkers were found dead in the areas between Damkyam, Manang and Thorong Pass, Mustang," said Mustang chief administration Baburam Bhandari.

Of those killed, four are Canadians, three Polish, one Israeli and one Indian.

The trekkers were caught by avalanche and snowfall while coming down from Mustang to Manang.

Deputy Inspector General of Police Ganesh Rai said a total of 38 trekkers trapped in the Thorong Pass area were rescued by the Nepali army on Wednesday and some trekkers are still missing.

Search and rescue operations have resumed after being briefly halted due to bad weather on Wednesday morning.

Cyclone Hudhud caused heavy snowfall in Nepal's northern districts and brought rain to the rest of Nepal.

Heavy rain led to the cancellation of more than 70 domestic and international flights to and from Kathmandu on Tuesday.

A number of international flights scheduled to land at Tribhuvan International Airport were diverted to India.
India's Jet Airways, Indian Airlines and Buddha Air cancelled their international flight services while China Southern Airlines was diverted to Lucknow in Indian state of Uttar Pradesh.
