A Colombian music festival ended in disaster on Sunday (05Jan14) after four people suffered minor injuries when a botched fireworks display set part of Dutch Dj Nicky Romero's stage ablaze.

The house music star was performing at the Summerland Festival on the eve of his 25th birthday (06Jan14) when the fire broke out, forcing him to cut short his set.

Emergency services were called to put the flames out and Romero took to his Twitter.com page after the incident to express his shock, writing, "Omg (Oh my God) the fireworks shot the stage on fire, I hope no one got hurt..."

Responding to a fan who was worried about his safety, he replied, "I was lucky I'm okay!"

Meanwhile, friends of his pal Dimitri Vegas, who was also onstage at the time, were not so lucky - he tweeted, "half my crew & @wolfpack (fellow Dj) got impact burns all over their bodies & 2 even got rocketexplosion on the ear (sic)."

The blaze didn't stop organisers from pressing ahead with the final act of the night - Colombian Dj Moska returned to the stage after the fire was extinguished to bring the three-day event to a close.

The explosion wasn't the only problem at the Cartagena bash - more than 100 people had to be treated for drug-related issues last Friday night (03Jan14).

The Summerland Festival also featured weekend performances from Afrojack, Armin Van Buuren and Nervo.
