AlQa'dah 23, 1432, Oct 21, 2011, SPA -- More than 70 people were injured when a high-speed passenger ferry hit a concrete mooring pillar as it was leaving one of Hong Kong's outlying islands Friday, media reports said, according to dpa. Some of the casualties, including a critically injured woman in her 70s, had to be airlifted to hospital on Hong Kong Island, according to broadcaster RTHK. Others were transported by ferry to the central business district where they were helped into 18 ambulances and taken to hospital. Some were treated in a clinic on Cheung Chau island, where the accident occurred. The catamaran ferry, owned by New World First Ferry, had about 140 people onboard when it slammed into the concrete mooring as it departed for the central business district on Hong Kong Island. -- SPA
