Thousands of anti-government protesters have turned out for marches in Hong Kong despite pouring rain, spurred into action by a government ban on masks, APA reports citing BBC.
Rioting broke out in some places, with new attacks on businesses. Police fired tear gas and used truncheons.
Many protesters covered their faces in defiance of the ban, upheld by the High Court on Sunday. Masks are a new focus in months of pro-democracy protests.
Metro services were attacked on Friday but have partially resumed.
Police use of live bullets against protesters this week, leaving two people injured, has also fuelled the unrest.
Chief executive Carrie Lam introduced the ban by invoking powers dating back to colonial rule by the British.
