(BBC) “Fast-time learning” from the attack on Manchester Arena led to several changes in how UK counter-terrorism teams work, the inquiry into the bombing has heard.
The inquiry into the attack of 22 May 2017, which killed 22 people, was told senior officers reviewed what happened five days later to learn from it.
Their 21 recommendations had mostly been implemented, the hearing was told.
A senior officer said that at the time, counter-terrorism focused on the nature, not the timing, of a threat.
Twenty-two people were killed and hundreds more were injured as they left an Ariana Grande concert on 22 May 2017.
