The wreckage of a passenger plane that went missing in Nepal on Wednesday with 23 people on board has been found, the aviation minister said.

"The wreckage of the plane was found in a completely burnt state in Solighopte in Myagdi district," Aananda Prasad Pokharel told AFP, adding that bodies could be seen scattered around the wreckage.

The airline revised its earlier number of 21 on board the Twin Otter plane.
