On 29 November 2019, a man armed with a knife attacked individuals participating in a prison rehabilitation conference at Fishmongers’ Hall, located at the northern end of London Bridge. Occupants of the building hosting the conference physically confronted the assailant, forcing him to leave the premises and continue onto the bridge, where police officers shot and killed him. Officials stated that the assailant was also wearing a fake explosives-laden vest during the attack. The man killed at least two people and wounded three others in the attack. He had been convicted and jailed in 2012 for planning and raising funds to commit acts of terrorism and was released from prison in December 2018. While the Islamic State group claimed affiliation with the assailant, U.K. officials believe that the man acted alone and may have planned the attack less than 24 hours in advance.
