In Australia, firefighters are battling to contain a blaze burning out of control in Sydney’s Royal National Park.

The Australian Rural Fire Service says the bushfire threatens the main access road to the park in Sydney’s southern outskirts.

An emergency warning has been issued with evacuation measures being put in place for around 1,000 visitors inside the park.

Water-bombing helicopters are used to slow down the fire while rescue teams struggle to arrange a sea escort for hundreds of people.

Authorities have not yet concluded the cause of the blaze.
