"I am so moved," she wrote. "Moved by the grief of those families who lost loved ones. Moved by the pain of those who were injured and the fear of their families. Moved by the great heroism as I watched so many brave Indianapolis fans actually run toward the stage to try and help lift and rescue those injured. Moved by the quickness and organization of the emergency workers who set up the triage and tended to the injured.

She continued: "There are no words to process a moment of this magnitude and gravity. There are only prayers for peace in the hearts of the bereft, and prayers of thanksgiving for those who were spared or safe. A piece of our heart is left in that grandstand. May God provide peace and healing to the people of Indianapolis."

The tragedy, which was caused by a burst of high winds and also left dozens injured, occurred shortly before the country duo was set to perform

Opening act Sara Bareilles, who had finished her set when the bad weather hit, also expressed her condolences.

"I'm speechless and feel so helpless," she wrote on Twitter. "Please send love and prayers to Indianapolis tonight. My heart aches for the lives lost."
