No arrests have been made, the authorities said.

Police in Germany are on the hunt for a suspect who allegedly killed and wounded several people at a music festival Friday night in Solingen, investigators said.

Three people were confirmed killed as of 7:20 p.m. ET, German police said.

The "Festival of Diversity" was being held throughout the weekend to celebrate Solingen's 650th anniversary, according to the festival's organizers.

Tim Kurzbach, Solingen's mayor, posted a message on Facebook stating the town was in shock, fright and great sadness.

"We all wanted to celebrate our city anniversary together and now we have to mourn the dead and injured. Breaks my heart that there was an assassination attack on our town. Tears in my eyes when I think of those we have lost. I pray for all those who are still fighting for their lives," he said in a post written in German.

"Also to all the people who had to witness this, my great sympathies must have been terrible pictures. I thank all the emergency and security forces for their service. I ask that if you believe pray with me and if you don't then hope with me," he added.
