In the UK, police are investigating a number of stabbings at the famous Notting Hill Carnival.
Officers were called after a spate of violent incidents were reported close to the festival as thousands of people attended the final day celebrations.
It's Europe's largest festival of its kind and was being held for the first time since the pandemic.
A section 60 order was imposed just before half past 9 which allowed officers to stop and search members of the public without suspicion.
