A British expedition leader has told a coroner's inquest how he tried to gouge a polar bear's eyes to stop it attacking teenagers on an Arctic adventure trip.

Michael Reid recounted the attack Tuesday at an inquest into the death of 17-year-old Horatio Chapple, who was mauled as he slept in a tent.

Four others were injured in the 2011 attack in Norway's Svalbard archipelago.

Reid told the inquest in Salisbury, southern England, that he tried to shoot the bear, but his rifle did not go off.

Reid said the bear then attacked him, and "I thought the weakest part is the eyes so I tried to take out the eyes with my fingers, but was unsuccessful."

Reid grabbed the gun again. This time it fired, killing the bear.
