Three Bangladeshi students have been killed and four injured in a car crash at Kakadu National Park, in the Northern Territory of Australia, reports ABC News.

The car carrying seven people rolled on the Kakadu Highway about six kilometres north of Cooinda Lodge at about 12:30pm (local time) Saturday.

Four injured patients were transferred to Darwin by CareFlight just before 5.00pm and then to the Royal Darwin Hospital. They are now in stable condition, the hospital says.

Two of the injured people might have limbs amputated, and another had a severe head injury, a spokesman told the ABC News.
