One thousand people from the European Union are missing in Nepal and 12 are confirmed dead, nearly a week after a devastating earthquake, the head of the EU delegation here said on Friday.
"We don't know where they are, or they could be," Ambassador Rensje Teerink told reporters, adding that those unaccounted for were mostly tourists in the Langtang and Lukla areas.
Langtang is a trekking region to the north of Kathmandu that has been hit by a huge avalanche and mudslides, while Lukla is the jumping off point for walkers and climbers making the nine-day trek to Everest base camp.
Meanwhile, more than 100 British survivors were reunited with loved ones in London early on Thursday, after flying out of Nepal.
One dual national has been confirmed dead in the earthquake.
There were strong emotions for Italians flying into Milan minus two members of a climbing group who had lost their lives in the disaster.
More than 200 mainly French nationals also arrived on a flight to Charles de Gaulle Airport in Paris, with many thoughts turned towards those left behind.
“I feel like I’m going to break down,” said one woman, struggling to hold back the tears.
Foreign Minister Laurent Fabius, who was at the airport to meet those returning, confirmed a third French death. Efforts continue to contact more than 260 French nationals still unaccounted for.
Nepal, struck by a huge earthquake on Saturday that has killed more than 6,000, is a popular destination for trekkers and climbers.
Rescuers have struggled to get to remote areas of the mountainous country popular with climbers to look for survivors, with fighting between tourists and locals marring efforts to airlift hundreds of trekkers to safety.
Diplomats are finding it hard to trace the missing because many backpackers do not register with their embassies when they arrive in the country.
