Fierce fighting has broken out on the streets of Hong Kong with hundreds of anti-globalisation protesters storming police lines to try and break into a WTO meeting.The stand-off is said to have been led by a hard core of South Korean farmers who say free trade is ruining them. The group got very close to the convention centre but pulled back after security forces fired tear gas. There are reports of about 50 injuries and of 900 demonstrators being detained by police. Areas close to the WTO gathering were blocked off and some transport links closed to prevent protesters from moving around the city. Security has been beefed up in Hong Kong for the talks – an estimated 10,000 anti-globalisation protesters have converged on the city. And whilst the fighting raged outside – inside the convention centre rich and poor nations have been been pitted against each other as ministers battle to find an elusive world trade deal.
