London Mayor Sadiq Khan said he is "not complacent" about an attack happening closer to home as he attended the vigil honouring the victims of the Orlando shooting.
Paying his respects to those affected, he said the attack on the LGBT community is an attack on "our freedoms and values".
There were services held around the world to remember the lives lost and to also support the LGBT community, including the main event in Soho where a vigil was held .
The SSE Arena in Wembley also lit up the front of the arena with the colours of the rainbow flag on June 13 in tribute to the victims of the Orlando shootings.
The shootings took place at Pulse nightclub in Orlando when Omar Mateen killed 49 people at the club on Sunday (June 12) night, which injured at least 53 others.
LGBT flags were also raised in west London to remember the victims of the attack, with both Hammersmith and Fulham and Ealing councils raising the flag above their town halls, at half mast, on Monday (June 13).
ISIS has claimed responsibility for the attack, with the gunman, Omar Mateen, said to have been potentially radicalised.
