At Hong Kong's Halloween celebrations
this year face masks of Chinese President Xi Jinping
and Hong Kong's leader Carrie Lam
replaced the usual pumpkins and skeletons.
Halloween has long been a popular festival
in this Asian financial hub, but this year the holiday
has a new political significance.
In an attempt to quell almost five months of protests,
the government banned wearing masks in early October.
Hundreds of demonstrators wearing protest-themed mask
and costumes participated in an unauthorised march
through the city's financial district to a popular bar
district before police fired tear gas.
Around 200 protesters have been arrested so far
for violating the anti-mask law.
Hong Kong has plunged into its worst political crisis
in decades, triggered by a now withdrawn
controversial extradition bill.
