Authorities have charged nine people after a protest at London City Airport disrupted travel for thousands.

The group, Black Lives Matter, claimed responsibility on social media for the protest Tuesday, and said that airport expansion plans consign the local community of Newham to environmental degradation.

The nine were charged Wednesday with aggravated trespass and being unlawfully within a restricted area of the airport. All were released on bail to appear before Westminster Magistrates' Court on Sept. 14.

The demonstration was the second in as many months by the anti-racism activists, who blocked traffic leading to Heathrow and held other protests in several British cities. Activists say black men in Britain are unfairly targeted by law enforcement.
