Thousands of people spent the night out in the open air fearful of more aftershocks after another strong earthquake in Nepal claimed the lives of at least 66.
A U.S. Marine Corps helicopter carrying aid was reported missing in northeastern Nepal, US officials said.
Most casualties of the latest magnitude-7.3 quake were in the Dokha district, northeast of Kathmandu.
"People are terrorized. Everyone is scared here. They spent the night out in the open," said local government administrator, Prem Lal Lamichane.
Latest reports from the Home Ministry said at least 2,000 people had been injured.
Officials also said the rebuilding process could be hampered by landslides as the monsoon season intensifies over the next few months.
Two weeks ago the first devastating earthquake killed more than 8,000 people and injured more than 17,800.
