At 3pm people will gather to light candles and wave rainbow flags.

The vigil has been organised by the LGBT+ Society.

The flags outside Norwich City Hall are at half-mast. The building will be lit in rainbow colours from dusk, joining many other iconic buildings across the world, that will be illuminated.

On Sunday June 12, killer Omar Mateen, a security guard of Afghan descent, killed 50 people and injured 53 others in the worst mass shooting in the recent history of the United States.

He shot around a third of the 300 people in the Pulse nightclub using an AR-15 assault rifle before he was killed in a shoot-out with armed officers.

The 29-year-old had been on the FBI's radar since 2013, but was able to legally buy a handgun and a semi-automatic assault rifle which he used to carry out the massacre.

The Islamic State's radio channel on Monday called the Orlando mass killer 'one of the soldiers of the caliphate in America'.

Al-Bayan Radio, a media outlet for the IS extremist group, hailed the attack that left 50 people dead, saying it targeted a gathering of Christians and gays and that it is the worst attack on US soil since the September 11, 2001, terrorist attacks.
