Hong Kong: activists raise blank paper in protest against security law

Protesters have held up blank pieces of white paper to avoid using slogans banned under a new national security law in Hong Kong on Monday.

The law, which was imposed by China after anti-government protests last year, has made it illegal to shout slogans or hold up banners and flags calling for the city's independence.

Hong Kong police cleared the group of demonstrators who gathered in a shopping centre in the central business district.
