Australian naturalist and television personality Steve Irwin has been killed by a stingray during a diving expedition off the Australian coast.
Mr Irwin, 44, died after being struck in the chest by the stingray's barb while he was filming a documentary in Queensland's Great Barrier Reef.
Paramedics from Cairns rushed to the scene but were unable to save him.
Mr Irwin was known for his television show The Crocodile Hunter and his work with native Australian wildlife.
Police in Queensland confirmed the environmentalist's death and said his family had been notified. Mr Irwin was married with two young children.
I was so sad when I heard the news. His programmes were a joy to watch. May he rest in peace.
