INTERNATIONAL: Australian police on Tuesday recovered the bodies of a British national and his nine-year-old son killed in a landslide on a hiking trail in the Blue Mountains national park near Sydney.

A 50-year-old woman and a boy aged 14 remained in critical condition after surgery, while a 15-year-old girl is in hospital under observation, New South Wales state police said.

Rescuers took more than an hour to reach the site and a helicopter was used to retrieve the bodies, media reported. The British Consulate is assisting.

The Blue Mountains get about 4 million tourists a year, the most of any national park in Australia.

The walking track, which has been closed until further notice, was given a routine inspection a few days ago, New South Wales National Parks and Wildlife Service (NPWS) said in a statement.

"Unfortunately, it is not possible to predict and eliminate all natural risks such as rockslides, which can occasionally occur around the state," a NPWS spokesperson said.
