HONG KONG, China — Police fanned out across Hong Kong on Tuesday
in a bid to deter pro-democracy protests as the city marked communist China's 70th birthday, with local officials watching a flag-raising ceremony behind closed doors because of security concerns.
Authorities ramped up security checks ahead of the anniversary, shutting down two subway stations near government offices and conducting stop and searches in the streets and on public transport.
