HONG KONG—Hong Kong is preparing for a weekend of demonstrations, including a human chain at major subway lines on Oct. 18 and a democracy march on Sunday, the latest moves in more than four months of pro-democracy protests.
It has been two weeks since Carrie Lam, leader of the Chinese-ruled city, invoked colonial-era emergency laws banning face masks, hoping to quell protests. Instead, the city has been shaken by some of the most intense unrest to date.
