Isis has claimed responsibility for Saturday’s attack, although this has not been verified. In a statement published late on Sunday by the Amaq news agency, which usually carries its claims, it said:
"A detachment of Islamic State fighters executed yesterday’s London attack."
Metropolitan police assistant commissioner Mark Rowley said detectives were urgently investigating whether the three terror suspects were “assisted or supported” by a wider network.
The names of the three men have not been released. Police say they believe all the attackers were killed after armed officers “fired an unprecedented number of rounds” to shoot them dead during their attack on Borough Market.
One of the suspected attackers was described by neighbours as a married father of two who attended local mosques.
One neighbour told the Guardian she had reported the man to police two years ago after fears he was attempting to radicalise children.
