OSLO, Norway — A polar bear attacked a group of British students camping on a remote Arctic glacier as part of a high-end adventure holiday, killing a 17-year-old boy and injuring four other young people early today before a trip member fatally shot the bear.

Two of the wounded were hospitalized with severe injuries, said the British Schools Exploring Society, the organizer of the trip.

The attack took place on the Svalbard archipelago, which is home to about 2,400 people and 3,000 polar bears and attracts well-off and hardy tourists with stunning views of snow-covered mountains, fiords and glaciers.

The British Schools Exploring Society is affiliated with Britain's Royal Geographic Society and has run expeditions for young people to remote and challenging corners of the globe for at least 75 years.
