Several teams of Sherpas are for a British trekker who has been missing for a month. George Abboudi, 22, set off alone on August 5 for an 11-day trek in northern Nepal and has not been heard from since.
Due to several disappeared hikers in recent years, the government of Kathmandu announced last summer its intention to require all trekkers to hire a guide. The tourism industry opposed the requirement, and the measure has yet to be implemented.
