A shark attacked and killed a teenage boy Tuesday while he and a friend were body-boarding off Australia's eastern coast, officials said. The 16-year-old was about 50 meters from shore when the shark attacked around 8 a.m., lifeguard spokesman Stephen Leahy said. Police said the boy's friend was already out of the water when he looked back and saw his friend "in distress" and swam back to bring his friend to the beach. The victim suffered two large bites, one to the leg and one to the body. He died of extreme blood loss while lifeguards and paramedics tried to save him. "We had multiple paramedics en route to the scene as well as the rescue helicopter," New South Wales Ambulance spokeswoman Penelope Little told Sky News television. "But, tragically, the young boy has died at the scene."
