A teenage boy has been killed in a shark attack off the northern coast of New South Wales in eastern Australia, police say.
The 15-year-old was surfing when he suffered severe leg injuries at Wooli Beach, 630km (390 miles) north of Sydney, according to witnesses.
Nearby surfers came to help, including one who is reported to have tried to pull the shark away.
First aid was given on the beach but the boy died at the scene.
“Several board-riders came to his assistance before the injured teen could be helped to shore,” a police statement said.
