Rescuers are searching for nearly 1,400 people, most of them tourists, who are missing after a catastrophic flash flood hit Nepal and Tibet, thundering down valleys, obliterating entire villages and killing at least 356 people.

Efforts to locate those missing - including hundreds of people from India, the US, UK, Australia and Canada - have been complicated by the destruction of dozens of bridges and almost 25 miles (40km) of roads in the mountainous region popular with trekkers and pilgrims.
