The US military said Friday it expected to find no survivors after locating the wreckage of a helicopter that went missing with eight people on board in earthquake-devastated Nepal.

"We can confirm that we have located the wreckage... it is unlikely there are any survivors," John Wissler, commander of the joint task force investigating the disappearance, told reporters in Kathmandu, three days after the chopper vanished while delivering aid in a mountainous region.
