British police have named two of the three men suspected of carrying out the terror attack in London on June 3.
Khuram Butt, 27, was married with children and lived in Barking, east London, for a number of years.
London's Metropolitan Police said Butt was previously known to police and Britain's domestic spy agency, MI5.
"However, there was no intelligence to suggest that this attack was being planned and the investigation had been prioritised accordingly," police said in a statement.
Butt was a British citizen born in Pakistan.
The other attacker was named as Rachid Redouane, 30, who also went by the identity Rachid Elkhdar and was not known to police.
Redouane claimed both Libyan and Moroccan nationality.
Police say investigations were continuing into the identity of the third attacker.
The three suspects were shot dead by police officers within minutes after they drove a van into pedestrians on London Bridge and then attacked several people with knives in the nearby Borough Market nightlife neighborhood.
