A polar bear has mauled a 17-year-old British boy to death in the Arctic and injured four other UK tourists.
Horatio Chapple, from Wiltshire, was with 12 others on a British Schools Exploring Society trip near a glacier on the Norwegian island of Spitsbergen.
The four who were hurt, two severely, included two leaders of the trip. They have been flown to Tromsoe where their condition is stable.
