A small passenger plane heading to the Mount Everest region crashed in heavy rain Tuesday outside Nepal's capital, killing all 14 people aboard, including four U.S. nationals, a Briton and a Japanese tourist, officials said. The private Agni Air plane went down near Shikharpur village, about 50 miles (80 kilometers) south of Katmandu, area police chief Ram Bahadur Shrestha said. The German-built Dornier airplane was carrying 11 passengers and three crew members when bad weather forced it to try to return to Katmandu, according to a report of the Associated Press. Tri Ratna Manandhar of the Civil Aviation Authority of Nepal confirmed there were no survivors. Manandhar said there were four Americans, one Briton and one Japanese aboard, while the remaining passengers and crew were Nepalese.
