Protesters have threatened to "escalate their actions" if the Hong Kong government fails to withdraw its controversial extradition bill by 5 p.m. local time June 20, The Guardian reported June 19. Anonymous messages shared on social media also called for people to strike, close shops and stay home from school on June 21 if the now-suspended law isn't fully retracted. A few, more radical posts told protesters to come equipped with face masks and umbrellas to shield themselves from tear gas.
