London attack: Live updates

(CNN)Extra security was visible across London Monday as police carried out more raids at addresses in the city's east following the terror attack on the weekend.

Seven people were killed and dozens injured when three men -- later shot by police -- rammed pedestrians at London Bridge and randomly knifed people at Borough Market.
It was the third terror strike in the UK this year, after a man drove a car into pedestrians on Westminster Bridge in March and a bomb attack on an Ariana Grande concert in Manchester two weeks ago.
