Shanghai beefs up security measures at railway, subway and bus stations

Shanghai will step up security at railway stations with armed police officers, following a wave of violent attacks across the country, authorities said on Wednesday.

The effort coincides with the Fourth Summit of the Conference on Interaction and Confidence Building Measures in Asia, which the city will host on May 20 and 21.

The public security department and railway police will deploy armed patrols at the city's seven railway stations.
