Masked men attacked anti-government protesters in Hong Kong at a train station late Sunday, hitting them with sticks. Elsewhere in the city, police fired tear gas and rubber bullets to disperse protesters after some people vandalized the Chinese government's liaison office in the city, marking an overt challenge to China's authority over the financial hub. The clashes came after a peaceful march earlier in the day calling for an independent investigation into alleged police brutality in earlier protests. Organizers said 430,000 people participated in the sanctioned part of Sunday's demonstration; police put the figure at 138,000. A series of mass protests started last month against a proposal to allow criminal suspects to be extradited to mainland China, where the governing Communist Party controls the courts. The bill has been suspended but protesters want it fully withdrawn.
