A shark has fatally mauled a diver off an Australian tourist island, police say. Police said the 38-year-old man was spearfishing with a friend on Saturday when he was attacked near Rottnest Island.

It's the first reported shark attack since January, when a 12-year-old boy died after an attack in Sydney Harbour.
