A powerful 7.3 magnitude earthquake struck Nepal on Tuesday - the biggest aftershock to date of a quake which left more than 8,000 people dead less than a month ago.
The latest earthquake has left more than 90 people dead and thousands injured.
Meanwhile, search teams are trying to locate a US military helicopter which went missing during an aid mission with six Marines and two Nepali soldiers on board.
A US military team has confirmed that wreckage found in the mountains of Nepal is that of a missing Marine helicopter.
The US Pacific Command said the crashed UH-1Y Huey chopper was found around eight miles (13km) north of Charikot town, one of the areas worst-hit by two devastating earthquakes in the past month.
Spokesman Army Major Dave Eastburn said the site was still being assessed and an investigation was underway to try to establish how the craft came down. It had been assisting in the relief operation at the time it went missing.
He did not make any comment on the fate of the six Marines and two Nepali soldiers who were on board the helicopter at the time of the crash, but officials in Nepal have said there were no survivors.
