A small plane carrying 21 people went missing Wednesday while flying in a mountainous area in Nepal, authorities reportedly said. Tara Air Viking 9N-AHH Twin Otter was on an 18-minute flight when it lost contact with the control tower, the Associated Press reported.

The plane was reportedly traveling from Pokhara, 125 miles west of Kathmandu, to Jomsom, which is the starting point for trekkers going into mountainous areas. The plane was carrying 18 passengers, including two foreign nationals, and three crew members.

"Two helicopters are on a search-and-rescue mission," Pokhara airport official Yogendra Kunwar said, according to Reuters. "There is no trace of the aircraft so far."

Search has been underway for more than two hours but poor weather conditions are hampering the operations, Kunwar reportedly said. He added that there were no landing strips between the two airports where the plane was flying.

According to Kathmandu Post, a local newspaper, the two foreigners on board the plane are from China and Kuwait.
