Canadian woman among those killed in London Terror attacks

Police have searched two homes in East London today in connection with Saturday's terror attacks -- the van attack on London Bridge and the knife attack at the Borough Market.

Metropolitan Police Commissioner Cressida Dick says the investigation is advancing quickly and 12 people are in custody for questioning about possible links to the attackers.

Seven people were killed in the terror attacks and 48 were injured -- many critically.

Among those killed was 30-year-old social worker Christine Archibald of Castlegar, B-C.

Her family says she'd worked at a homeless shelter before moving recently to Europe to be with her fiance.
