Hong Kong’s border town of Sheung Shui was rocked by protest violence and chaos for hours on Saturday before police could clear the streets at night, following a major rally against mainland Chinese visitors and parallel traders. Police described the mostly young protesters as “highly organised” and well prepared to attack them with iron poles and other weapons which they distributed among themselves in advance. Sources said at least five police officers were injured in running battles with hundreds of protesters around the railway station in the afternoon, and there were also reports of journalists on the scene being injured.
