Police on Tuesday named the third attacker in the weekend terror assault in London amid mounting anger, two days before an election, over how the killers had apparently escaped surveillance.
With flags at half-mast, the nation fell silent at 11:00am (1000 GMT) to remember the seven killed and dozens injured on Saturday night — a mourning ritual now grimly familiar after two previous terror attacks in less than three months.
Police identified the third attacker as Youssef Zaghba, a 22-year-old Italian of Moroccan descent, a day after naming his accomplices as Khuram Shazad Butt, 27, a Pakistan-born Briton, and Rachid Redouane, 30, a self-described Moroccan-Libyan dual national.
Police also said they had made an overnight raid in east London and arrested a 27-year-old man early Tuesday. Twelve people arrested earlier have since been released without charge.
