MI5 accused of failing to sound alarm about terrorist Usman Khan

Inquest told security services should have shared intelligence about threat from Fishmongers' Hall attacker

The chief probation officer for England and Wales has accused MI5 of failing to sound the alarm about Usman Khan attending an event in London where he killed two people, an inquest has heard.

Sonia Flynn, the executive director of the probation service, said the security services should have stepped in when Khan's possible attendance at the event in Fishmongers' Hall was raised at a series of public protection, or Mappa", meetings MI5 attended.
