A drone has been sent up to help in the search for a missing US Marines helicopter which disappeared while working with the post-earthquake relief effort in Nepal.
Six Marines and two Nepalese soldiers were on board the UK1Y Huey chopper when is went missing near Charikot village, following a second devastating quake in a month for the country.
The search has come under some criticism for diverting resources away from relief efforts.
A battalion of around 400 Nepali soldier, along with US, Indian and Nepali military helicopters, are also being used in the search, with infrared cameras searching for hotspots and any signs of life.
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 Correspondent Dan Rivers speaks to a family who survived the latest tremors:
A US Marines helicopter missing in Nepal with eight on board may have come down in a river, the Nepali army has been told.
A senior officer said it had received information that the chopper, which was participating in earthquake relief operations, may have come down in the Charikot area hit hard by an earthquake.
Major Rajan Dahal said 400 soldiers are taking part in the search.
"The info we have is that it is down in one of the rivers, but none of the choppers has seen it yet," he said. "There are 400-plus of our ground troops looking for it also, by this evening, we might get it."

The death toll in Nepal's second deadly powerful earthquake has risen to at least 66.
Panic spread yesterday as the second deadly quake in three weeks brought down buildings weakened by the first disaster.
Among those dead are 17 in neighbouring India and one in Chinese Tibet.
Most of the reported fatalities were in villages and towns east of Kathmandu, only just beginning to pick up the pieces from the April 25 quake that killed more than 8,000.
Earthquakes never happen just once as Nepal has discovered with aftershocks potentially being felt days and even years later.
Their unpredictability means there is frequently very little warning as ITV News' Science correspondent Alok Jha explains.
