Four people are dead and reportedly 24 more injured after a stage collapsed tonight at the Indiana State Fair before the country band Sugarland was to perform.

The band tweeted their regrets on their official Twitter account shortly after the news broke. “We are all right. We are praying for our fans, and the people of Indianapolis. We hope you’ll join us. They need your strength,” they wrote.

High winds caused the collapse of a stage at the Indiana State Fair, Sara Bareilles, who is currently on tour with Sugarland, had just finished her set at the Hoosier Lottery Grandstand stage just before the collapse and also reacted on Twitter. “I’m speechless and feel so helpless. Please send love and prayers to Indianapolis tonight. My heart aches for the lives lost,” she wrote.

Janet Jackson is set to perform at the 17-day fair on Aug. 17, Train and Maroon 5 are scheduled for Aug. 18, and Lady Antebellum for Aug. 19. The fair has not said whether those concerts will continue as scheduled.
