In Hong Kong, police have besieged student protesters occupying Hong Kong Polytechnic University in a major escalation in the ongoing pro-democracy protests. Early Monday, police tried to storm the campus, but the students fought back with Molotov cocktails, slingshots and arrows. Over 100 people were arrested in recent days. Dozens of protesters have been injured by rubber bullets and tear gas. At least one police officer was injured by an arrow. Thousands of protesters have been arrested overall. Meanwhile, Hong Kong’s High Court has also ruled that the government’s ban on face masks was unconstitutional.
