A plane carrying 21 people, most of them Indian nationals, crashed into a hillside Monday as it descended to land at a Nepalese airport. Many of the passengers were en route to the Muktinath temple, a religious site in the mountainous region. A local police spokesman told reporters that the plane hit a muddy slope after attempting to land and ended up buried in the hillside, killing 13 Indian passengers and two Nepalese pilots. Among those being treated after the crash are two Danish passengers and two Indian infants. Accidents involving small aircraft occur occasionally in the treacherous mountain regions of Nepal.
