Drake is addressing the tragedy that occurred at the Astroworld music festival.

The rapper, who made a surprise onstage appearance at Travis Scott‘s Houston show on Friday, Nov. 5, took to Instagram on Monday, Nov. 8 to express his condolences. The concert left eight people dead and 25 others hospitalized, police previously confirmed.

Drake posted, “I’ve been trying to get my head around this terrible tragedy for the past few days,” Drake said, “I don’t like using this platform to share an emotion as sensitive as grief but that is exactly where I am.”

He said, “My heart hurts for all the people who have lost loved ones. They are all in my prayers and I am ready to help them. “May God have mercy on you all.”

More than a dozen concertgoers have filed lawsuits against Travis, as well as the event’s organizers. One concertgoer, Kristian Paredes, named Drake in a lawsuit that was also named Travis, Live Nation and Harris County Sports & Convention Corporation, citing negligence.
