Unknown gunmen opened fire at least two hookah bars in the German city of Hanau Wednesday night, killing eight people and wounding several others.

The New York Times, citing German public broadcaster Hessischer Rundfunk, said the suspects first opened fire at a shisha bar in the center of the city, about 15 miles east of Frankfurt, then drove to another neighborhood, where they killed five more in another bar.

Police said the suspects fled in a “dark car” and launched a large scale search.
