An armed man wearing a mask is reported to have opened fire at a cinema complex in western Germany, the BBC reports.
German media report that at least 20 people have been injured in the attack at the Kinopolis complex in Viernheim, near Frankfurt.
They say the gunman is inside the complex and surrounded by armed police, who have sealed off the area.
It is unclear whether he is alone or if he has taken hostages.
