Undeterred by a police ban, hundreds of thousands of protesters marched across Hong Kong on Sunday in opposition to the government's anti-mask law.
Pro-democracy demonstrators blocked roads, set fires and vandalized Chinese banks and subway exits, expressing strong anti-Chinese sentiment.
And again familiar scenes of unrest were seen, as riot police fired water cannons and tear gas at demonstrators.
Hong Kong government implemented the anti-mask law two weeks ago.
Recent so-called "white terror" attacks have further escalated tensions in Hong Kong.
Last week, the leader of a Hong Kong pro-democracy group was smashed in the head with hammers and spanners by at least four non-ethnic Chinese assailants in Mong Kok.
