Bad weather hampered rescue operations for a plane with 22 people aboard that went missing in Nepal on Wednesday, dpa quoted officials as saying. Two rescue helicopters dispatched from Kathmandu to search for the missing aircraft were forced to make an emergency landing because of the weather. The Twin Otter was carrying 19 passengers and three crew when it disappeared from radar screens five minutes after taking off from Lamidanda Airport in north-eastern Nepal's Khotang district. At least one foreign citizen was on the Kathmandu-bound aircraft, flight operator Tara Air said. Most of the passengers were returning from a pilgrimage to a Hindu shrine.
