Christian Social Union party urged the federal government to take decisive action to improve security after the attacks.
Germans are full of fear and need answers from their politicians after four violent attacks in less than a week, two of which have been linked to Islamistic terrorism, Bavarian state premier Horst Seehofer said on Tuesday.
"We need more security in Germany," Seehofer, leader of Bavaria's conservative Christian Social Union party, told a news conference, urging the federal government to take decisive action to improve security after the attacks.
"People are riled up, full of fear, and that is completely understandable. They need reliable answers from politicians and not endless debates and justifications," he said
