Channel 4 News has apologised for naming the wrong man as the suspect in the terror attack on Westminster.
Parliament went into lockdown on Wednesday evening after a man mowed down pedestrians on Westminster Bridge, before fatally stabbing a police officer in New Palace Yard.
Five people - including the perpetrator - died and up to 40 were left injured in the wake of the attack.
As the events unfolded at Westminster, senior home affairs correspondent Simon Israel quoted from a source which named an Abu Izzadeen as the perpetrator.
However, as the broadcast continued, the programme was contacted to be informed they had made a mistake, as Izzadeen is currently in prison.
As a result, they did a backtrack live on the air and later released a statement to apologise for the mistake:
Simon Israel also accepted responsibility for the mistake via his personal Twitter account.
The suspect in the assault on Westminster, who was shot dead shortly after he attacked PC Keith Palmer, has not yet been named.
