Hong Kong: Eighty people have been injured after a high-speed ferry travelling from Hong Kong to Macau hit an "unidentified object" in the water, according to Hong Kong's marine department.
"Information received from the Marine Department suggested that 80 people on the ferry were injured. Among them four were classified as seriously injured," a spokesman for the Hong Kong government said.
The accident happened at 1.20am (0420 AEDT) on Friday near one of Hong Kong's small outlying islands Hei Ling Chau, the spokesman said.
There were 105 passengers and 10 crew members aboard, with no reports that anybody was missing, he added.
"There was suddenly a loud bang. The ferry was thrown upwards. Then many passengers were thrown out from their seats," one passenger, named as Mr Wong, was quoted as saying by Hong Kong's Apple Daily news website.
After the accident the ferry sailed back to Hong Kong Island's downtown Sheung Wan terminal where a dozen of ambulances were waiting to tend to the injured, he said.
RTHK news website showed a passenger on a stretcher surrounded by emergency staff.
A government spokesman said there were no further details on passengers' injuries.
Local television footage appeared to show the ferry being towed back to the terminal.
"We only know that it sailed back but how it did so we are not sure," a government spokesman said.
