After a gunman opened fire in Pulse, a popular gay nightclub in Orlando, Florida, on Saturday night, the world is showing its solidarity in myriad - and rainbow - ways

It's been deemed the worst mass shooting in US history, with 50 people dead and another 53 injured after 29-year-old Florida local Omar Mateen opened fire. As the world reels from the blatantly homophobic attack, thousands from across the globe have gathered to show their support for victims' loved ones and the broader LGBT community.

Landmarks across the world glowed in the colours of the rainbow, from the One World Trade Centre in New York to Sydney's Harbour Bridge, Tel Aviv City Hall in Israel to New Zealand's Michael Fowler Centre. Makeshift memorials with rainbow flags, flowers and candles have been set up in cities as far afield as Bangkok, Berlin and Amsterdam. We've selected a few of the most touching tributes in the gallery above, but for more, check out the #PrayforOrlando hashtag on social media.
