“Officers from the Met’s Counter Terrorism Command investigating the London Bridge terror attack entered two further addresses -- one in Newham and another in Barking,” police confirmed.

Police also said a number of people had been detained, but did not give further details. The detainees’ names would be released as soon as “operationally possible,” police added.

Meanwhile, the first name from among the seven fatalities from Saturday’s attack in central London was released on Monday.

Canadian woman Christine Archibald died on London Bridge after being struck by a van reportedly driven by the terrorists on Saturday night. Canadian Prime Minister Justin Trudeau said he was “heartbroken” by the death.

Twenty-one of the injured are still in a critical condition, according to health officials.

Police said at least four officers were hurt during Saturday’s attack. Three assailants were shot dead at Borough Market after they ran over pedestrians on London Bridge before going on a stabbing spree.

A large police cordon is still in place around Borough Market and London Bridge. London Bridge station -- a major transport hub -- has since been reopened.

Meanwhile, a website associated with the terrorist group Daesh claimed responsibility for the third major terror attack in the U.K. in the last three months.
