At least 100 injured in Hong Kong ferry accident: authorities

At least 100 people were injured late Sunday when a high-speed ferry travelling from Hong Kong to Macau hit an "unidentified object" in the water, according to authorities.

Pictures showed wounded people being stretchered off the boat, some wearing oxygen masks, onto a pier in Hong Kong's central financial district to waiting ambulances.

Authorities received a call at around 6:00pm local time (1000 GMT) warning the ferry carrying 163 passengers and 11 had lost power after an accident off Siu A Chau, near the larger island of Lantau.

"So far it is understood around 100 people have been injured," a government spokesman said in a statement emailed to AFP.

Local media reported a large rescue operation had been mounted involving air services, marine police and the fire department, before the boat was towed back to Hong Kong island.

An AFP reporter on the scene later saw some 20 ambulances waiting near Government Pier as passengers gave statements to police.

Passengers were quoted in local reports describing chaos as the boat lost power, leaving people bleeding and injured stumbling around in the dark.

The accident happened when the high-speed ferry hit an "unidentified object" in the water, according to the ferry's operator Shun Tak.

The safety of Hong Kong's waters was called into question after a fatal 2012 crash in which 39 people were killed when a high-speed ferry collided with a pleasure boat near Lamma Island.

A subsequent inquiry found a "litany of errors" contributed to the accident, the city's worst maritime disaster for over 40 years.

The tragedy shocked the Asian financial hub, one of the world's busiest ports, which had prided itself on its good safety record.

Last June, more than 50 people were injured when a Macau-bound ferry crashed into a seawall off the coast of the gambling enclave.
