With the tragic stage collapse at [article id="1669037"]Sugarland's Indiana State Fair show[/article] still fresh in the minds of concertgoers, Jared Leto sent precaution to [artist id="1231235"]30 Seconds to Mars'[/artist] fans at Belgium's Pukkelpop festival on Thursday night (August 18) as a storm passed through, knocking down several stages and causing at least three deaths and 71 injuries.

"CRAZY STORM AT PUKKELPOP IN BELGIUM - NOT SURE WE WILL BE ABLE TO GO ON STAGE - STAYED TUNED. SAFETY FIRST," Leto tweeted prior to his band's set.

Things took a turn for the worse a mere half-hour later, when Leto tweeted, "FOUR STAGES DOWN - STILL RAINING + THUNDER IF YOU ARE HERE PLEASE BE SAFE."

According to reports, Pukkelpop was hit with strong winds and rainfall at around 6:15 p.m. local time, which caused several structures and stages to collapse. Nearby trees were also uprooted, causing even more damage to the fairgrounds and hazard to the estimated 60,000 in attendance. Chokri Mahassine, the organizer of the three-day festival, told The Associated Press, "We have for now put the festival on hold until we understand the situation completely."

Shortly after the collapse, the 30 Seconds to Mars frontman took to his website to send sympathy to those affected by the events. "Our deepest thoughts and sympathies to the families and friends of those who lost their lives today at the show in Belgium. We are absolutely devastated that this celebration ended in tragedy," Leto wrote. "To those that were injured we are sending thoughts and prayers. Obviously under these horrible and dangerous circumstances, and out of respect for those who have passed, Thirty Seconds to Mars will not be playing. We love you all and hope tomorrow brings a better day."
