A fundraising page set up by Equality Florida has raised more than US$900,000 (NZ$1.2 million) in just 10 hours for the victims of the Pulse nightclub shooting in Orlando, Florida.
Fifty people were killed and 53 more were injured when a gunman attacked the nightclub on Sunday. The gunman, 29-year-old Omar Mateen, died after being shot by police.
"We are heartbroken and angry that senseless violence has once again destroyed lives in our state and in our country," said Equality Florida in a statement.
"Gay clubs hold a significant place in LGBTQ history. They were often the only safe gathering place and this horrific act strikes directly at our sense of safety.
"We make assumptions on motive. We will await the details in tears of sadness and anger," the statement said.
A message on the GoFundMe page says Equality Florida is working with attorneys and experts, including the National Center for Victims of Crime, to make sure the money raised is properly distributed to the victims and families of the attack.
More than 21,000 people have donated so far.
