Sydney Beaches Closed After Three Shark Attacks

In Sydney, Australia, there were three shark attacks in just one day.

A man in his 20s and a 12-year-old boy were badly hurt, while an 11-year-old boy was lucky and not injured.

The sharks are thought to be bull sharks, which were more active because of recent heavy rain.

The beaches where the attacks happened are now closed.

There have been other shark attacks in the area recently, including one that was fatal.

Authorities are warning people to be careful in the water.

An eyewitness helped keep the man alive by using his surfboard’s leg rope as a tourniquet.
