On 29 November 2019, Usman Khan (aged 28 at the time) perpetrated a stabbing attack inside Fishmongers' Hall on London Bridge. He murdered two and injured three others.

Khan was at the venue to attend an educational event for rehabilitating prisoners. With two knives taped to his wrists, Khan fatally stabbed his first victim inside the male toilets. He then fatally stabbed his second victim near the venue's main door.

Khan attacked others, with some confronting him and chasing him onto London Bridge. Armed police arrived and fatally shot Khan when seeing he was wearing a suicide vest IED, which was later identified as a hoax device.

In 2012, Khan was among a group of nine men convicted for their involvement in an al-Qaeda inspired plot targeting numerous locations in the UK, including the Jewish community. The cell planned to target the London Stock Exchange, sending five mail bombs to various targets in the run up to Christmas 2010 and launching a “Mumbai-style” attack.

Khan and some of the other co-conspirators were also closely linked to Anjem Choudary and al-Muhajiroun successor groups.

In December 2018, Khan was released on licence and wore an electronic tag to monitor his movements. He was reportedly prevented from entering London but was given special permission to travel by train from Stafford to London to attend the November 2019 event at Fishmongers' Hall.
