Hong Kong Court Rejects Challenge to Mask Ban; Protests Continue Agence France-Presse HONG KONG - Hong Kong police fired tear gas at pro-democracy protesters Sunday after tens of thousands hit the streets once more to defy a ban on face masks despite half the city's subway stations remaining closed. Large crowds marched through torrential rain in unsanctioned rallies on both sides of Victoria Harbor Sunday afternoon. Clashes soon erupted as police fired tear gas at protesters blocking roads and building barricades in at least three different locations. Protesters have staged unsanctioned flash mob rallies across the strife-torn city -- some vandalizing subway stations and shops -- after Hong Kong's leader outlawed face coverings at protests, invoking colonial-era emergency powers not used for half a century. Pro-democracy lawmakers went to the High Court on Sunday seeking an emergency injunction against the ban, arguing the emergency powers bypassed the legislature and contravened the city's mini-constitution. But a senior judge dismissed their injunction demand. .
