At least nine police officers and three demonstrators have been injured during clashes at an anti-lockdown protest in London's Trafalgar Square - which saw 16 people arrested. The crowd of thousands threw bottles at the officers and chanted "pick your side", while police used batons against them and left some with visible injuries. Two of the officers injured needed hospital treatment, the Metropolitan Police said. The force said the arrests were for offences including breaching coronavirus regulations, assaulting a police officer, public order offences and violent disorder.

A car drove through dueling demonstrations involving Black Lives Matter protesters and counterprotesters on Imperial Highway in Yorba Linda, injuring at least one person.
