Thousands of people attended vigils held in Orlando and all over the world to honour the victims of the worst mass shooting in U.S. history, which left 50 people dead and another 53 injured.

Besides the U.S., vigils were held in countries like the United Kingdom, Australia, France and Germany to mourn the people killed in the attack, according to a BBC report.

Thousands of people gathered at the lawn of the Dr Phillips Center in Orlando to pay their respects to the victims of the mass shooting, ABC News reported, citing the Associated Press. According to some in the crowd, the Pulse nightclub played an important part in the lives of gays and lesbians. AP quoted a former employee of the club, Cathleen Daus, as saying: "Pulse gave me confidence, made me realise I was normal and so much like everyone else." A makeshift memorial has been set up for people to leave candles, flowers and notes for the victims.

BBC quoted a Muslim cleric who attended the event in Orlando as saying that the Muslim community commiserated with them against "the ideology of hatred, death and destruction".

Bernie Sanders, the Democratic presidential candidate, joined hundreds of people from Burlington to City Hall Park at a march and vigil organised by the Pride of Vermont. He reportedly encouraged everyone to help "create the kind of nation based on love that we all know we can become."

According to a report by the Telegraph, singer Lady Gaga read out names of the victims of the deadly attack at a candle-light vigil held in Los Angeles on Monday. Gaga was quoted by the daily as saying: "You all have been feeling a tremendous range of emotions since we've all heard about this horrible, hateful attack on Orlando."

According to Reuters, thousands of people gathered in the Soho neighbourhood of London to mourn the death of the shooting victims. They held a two-minute silence at the vigil. As the clock struck six, bars halted operations, crowds went quiet and numerous balloons were let off to commemorate those killed. Sadiq Khan, the mayor of London, was also present at the vigil.

The Sydney Harbour Bridge in Australia and the Eiffel Tower in Paris lit up in colours of the rainbow to honour the victims of the attack, BBC reported.
