MIAMI -- Organizers of a much-hyped music festival in the Bahamas cancelled the weekend event at the last minute Friday after many people had already arrived and spent thousands of dollars on tickets and travel.

Fyre Festival organizers announced the cancellation of what they previously billed as a "once-in-a-lifetime" concert along the lines of the Coachella Valley Music and Arts Festival in Southern California. People had already begun arriving in the Exuma islands for the first of two weekends that was to include performances by Blink-182 and others.

A statement cited "circumstances out of our control," for inability to prepare the "physical infrastructure" for the event in the largely undeveloped Exumas. Photos published on social media showed tents, wooden stalls and portable lavatories had been brought in for the festival, which was produced by a partnership that includes rapper Ja Rule.

"I'm heartbroken at this moment," Ja Rule, whose real name is Jeffrey Atkins, said on Twitter. "I wanted this to be an amazing event. It was not a scam as everyone is reporting."

The organizers said they were working to arrange charter flights to Miami for people who had already arrived in Exuma and said inbound flights had been cancelled. "I don't know how everything went so left but I'm working to make it right," the rapper said.

The Fyre Festival had promised "culinary delights and luxury" over this weekend and the second one in May. Organizers had relied on models and other minor celebrities to heavily promote the festival as a glitzy destination event. It was unclear from the website if the second weekend would also be cancelled.

The Bahamas tourism ministry had expected it to be one of the largest such events ever held in the island chain east of Florida. But attendees complained bitterly about disorganization, a lack of accommodations and inadequate food in social media posts.
