Police believe Khuram Shazad Butt, 27, and Rachid Redouane, 30, both from Barking, east London were the two of three attackers involved in the London strike on Saturday.
Seven people died in the attack, while 48 were injured. 30 people were kept in hospital through Sunday.
12 people have been arrested in connection with the attack, after police raids took place in Barking. 11 of these were at the one address.
Seven of the arrests were women. ISIS have claimed responsibility for the attack
The attackers hired a white Renault van to carry out the attacks on London Bridge and at Borough Market.
According to ABC News on Monday morning, one of the attackers, Khuram Shazad Butt, was involved in a 2016 documentary called “The Jihadist Next Door” on the British Channel ‘4’.
He was known to authorities before the attack.
The attack shines light on prime Minister Theresa May during the final days of the election campaign in Britain.
May reduced the ranks of police officers during her time as home secretary. Many have proposed that May resigns, which is an idea supported by Labour Party leader James Corbyn.
He said the best thing to do was to vote her out.
“We’re calling for a restoration of police numbers, and there’s a call being made for her to go, because of what she’s done on the police numbers,” said Corbyn.
On Monday, London bridge re-opened to the traffic, as a sign of normality returning to the city. Most underground stations around the city also re-opened.
