Two dockers were taken to hospital last night after a lump of iron fell on their heads at the strike-hit Kwai Tsing container port. They were operating a machine at the dock - where 450 dockers have been on strike for over a month for better pay and conditions - when the accident happened. The men were put in an ambulance and taken to Princess Margaret Hospital. Both were conscious. The lump of iron was 20cm square, a police spokesman said. It is believed to have been part of the locking mechanism from a crane used to lift containers. While there was no indication last night whether the accident was connected to the strike, the four terminals at Kwai Tsing operated by Hongkong International Terminals (HIT), part of Li Ka-shing's business empire, have had operational problems since the strike began. The main contractor for HIT caught up in the dispute said on Thursday it had only been able to hire 50 dockers to replace the strikers. It was not known yesterday whether the injured dockers were among those newly hired. Meanwhile, police are considering legal action against people who scuffled with officers and disrupted traffic in Central on Friday night during an unauthorised march to Government House by striking dockers and their supporters.
