Since this happened less than an hour ago, reports are murky about the cause, but the mayor has been quoted to say that it was an "explosive device." The Bavarian Interior Minister Joachim Herrmann is on the scene--he was involved with the last attack a week ago.
The area has been sealed off by law enforcement around Eugene's Wine Bar, according to the Nordbayem.de news website reported.
The interior ministry believes the explosion was intentional, contradicting initial reports suggesting it was a gas explosion and certainly not terrorism, as many assume correctly of late.
Ansbach Mayor Carda Seidel told journalists the explosion was caused intentionally with a device.
Ansbach's central square is packed with emergency vehicles and a town house is being drafted as an operations center.
