Hong Kong unanimously passes new national security law

The package, known as Article 23, punishes offences including treason, sabotage, sedition, the theft of state secrets, external interference and espionage with sentences ranging from several years to life imprisonment.

Hong Kong's leader John Lee said the law would come into effect on Saturday and called it a "historic moment for Hong Kong".

The new slate of laws comes on top of an earlier, China-imposed national security law that has been used to jail pro-democracy activists and triggered sanctions from the United States, including against Lee.
