People in Hong Kong could face life in jail for breaking a controversial and sweeping new security law imposed by China.
The legislation came into force on Tuesday but the full text was only revealed hours afterwards.
It was brought in by Beijing following increasing unrest and a widening pro-democracy movement.
Critics say the new law effectively curtails protest and undermines Hong Kong’s freedoms.
Hong Kong’s leader, Carrie Lam, defended the law, saying it filled a “gaping hole” in national security.
Details have been closely guarded and the Beijing-backed politician admitted she had not seen the draft before commenting.
The UK, EU and Nato have all expressed concern and anger, while pro-democracy groups have started to disband amid fears of immediate reprisals.
