Hong Kong police have deployed tear gas against demonstrators who've once again poured into the streets to demand the cancellation of an extradition bill.
But this time, there's a twist.
Some of the protesters have alleged that police are working with gangsters in white T-shirts, who have attacked anti-extradition-law activists with impunity at the Yuen Long transit station.
Videos of the T-shirted hooligans have appeared on Twitter today. (See below.)
Meanwhile, the Hong Kong Police Force has claimed that some protesters hurled bricks and petrol bombs at officers in the Sheung Wan district.
This allegedly continued after warnings were issued.
All of this comes two days after police announced the discovery of explosives following a raid in the Tsuen Wan district. Three men were arrested.
Earlier this month, Hong Kong's chief executive, Carrie Lam, insisted that the controversial extradition bill is "dead".
But it hasn't been been fully withdrawn and still exists in the legislative program until next July, according to pro-democracy activist Joshua Wong and others.
If the law is passed, it would legalize the extradition of people from Hong Kong, Macau, and Taiwan to face trial in mainland China for serious offences.
Protesters vow to continue taking action until the extradition law is withdrawn.
Below, you can see what's being said on social media about today's protest.
Prior to the demonstration, various pro-democracy activists, artists, and celebrities issued a videotaped manifesto in English listing five demands.
1. Fully withdraw the proposed amendments.
2. Rescind the characterization of the movement as a riot.
3. Drop all charges against anti-extradition protesters.
4. Fully investigate and hold accountable abuses of power in the Hong Kong Police Force.
5. Dissolve the Legislative Council and implement universal suffrage.
Four young people have died since protests began this year.
