Protests have broken out in Hong Kong during its first day under controversial national security laws imposed by Beijing, and after China confirmed that some suspects could be extradited to the mainland under the new rules.

On the 23rd anniversary of the handover from Britain to China, crowds defied a ban on protests and gathered on the streets of the busy shopping district Causeway Bay, where there were large numbers of riot police.
