A mass shooting at a cinema in Viernheim, Germany, has left at least 25 people injured, German public TV reported Thursday.
Viernheim is in western Germany, near Frankfurt.
The shooter entered the cinema, apparently heavily armed, around 3 p.m. local time, authorities said.

"We don't know who the shooter is or what kind of weapons he has, but the possibility this could be a terror attack is crossing the minds of people here in Germany," CNN's Atika Shubert reported from Berlin.
It's not clear how many of the injured were shot, and how many may have been hurt in other ways.
The cinema is part of a major shopping center, home to more than 100 businesses. The complex hosts 20,000 visitors daily, according to its website.
Mass shootings are rare in Germany. But in 2002, a gunman opened fire at a high school in Erfurt, killing 16 people -- 13 staff members, two students and a police officer. In 2009, a gunman dressed in military gear killed 15 people in a spree that started at a school and spanned two small towns near Stuttgart.
