Bars along Old Compton Street in Soho will stop service at 7pm on Monday (June 13) to honour the victims of a mass shooting in Orlando, Florida.

Hundreds of people are expected to gather to hold hands, observe a minute's silence, and release a balloon for each of the 50 victims of the attack.

The event, called London Stands With Orlando, already has over 2,000 responses on its Facebook page with people saying they will attend, including representatives from London's Pride festival.

50 people were killed and a further 53 injured when Omar Mateen opened fire inside Pulse, an LGBT+ nightclub in Orlando, during the early hours of Sunday (June 12).

The death toll makes this the worst mass shooting in American history.

Pride in London also confirmed that they would hold a one minute's silence at the Pride Parade event on Saturday June 25 to honour the victims of the attack.

In a statement, Pride in London director, Mohsin Zaidi, said: "This is a devastating and barbaric attack that will be felt across the LGBT+ community and all over the world. Pride in London stands shoulder to shoulder with all the people who have been touched by this tragedy.

"It seems that people lost their lives at the hands of someone who despised our way of life. Pride can be our moment to stand tall in the face of such brutality."

Jeremy Joseph, owner of the four G-A-Y venues across the country, warned customers to clubs to be aware of danger and stay safe during this time. He said: "There's a concern now that there's going to be a copycat person who's going to attempt this here.

"We're trying to get customers to be vigilant."
