The nurse, who works at Princess Alexandra Hospital in Harlow, Essex, told the Press Association: “My wife’s auntie and uncle, and their granddaughter and her husband are missing, and my godson as well.
“They’re gone. The speed the water came, they couldn’t be saved, they were just swept away.
“The town and the villages were swept away, it’s a tragic thing.”
Bishal Nath Upreti, president of the Nepal Centre for Disaster Management, described the scene as like a “tsunami from the sky” and that villages have been “completely wiped out”.
Nepalese officials said bridges have been destroyed and nearly 25 miles of roads have been damaged, which has complicated search efforts.
