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 Nepalese Home Ministry official has said he fears the ongoing rescue efforts to help people affected by Tuesday's earthquake have been delayed by the search for a missing US Marines helicopter.
Speaking after it was reported that 400 soldiers and six helicopters had joined the search for the missing chopper Laxmi Prasad Dahal told Reuters "the work of sending relief and rescuing the injured people to hospitals has been delayed due to this."
According to reports a Pentagon spokesman confirmed this evening that he has heard nothing to verify reports the helicopter had been found and said the aerial search would resume on Thursday.
ITV News has travelled with a helicopter team to rescue a woman in a Nepalese village as the true scale of the latest tragedy emerges.
