HONG KONG—Hong Kong police said on Aug. 4 they arrested more than 20 people after violent clashes with anti-government protesters overnight, as the Chinese-controlled territory braced for more protests and a general strike aimed to bring the city to a halt.
On Aug. 3, police fired multiple tear gas rounds in confrontations with black-clad activists in the city’s Kowloon area, the latest escalation after more than two months of protests against a proposed bill to allow people to be extradited to stand trial in mainland China.
