BERLIN, July 25 (Xinhua) -- German Interior Minister Thomas de Maiziere said Monday a terrorism link to the suicide attack in Ansbach could not be ruled out.
De Maiziere told a press conference here that the investigation on the attack outside a music festival in Ansbach, a city in southern German state of Bavaria, was still in its early stage.
"It could not be excluded that it had a connection with international terrorism," he said. The attacker, a 27-year-old Syrian denied asylum in Germany, might also have psychological instability, it was reported. It could be "a combination of both," De Maiziere added.
Twelve people were injured during the suicide bombing.
Bavarian Interior Minister Joachim Herrmann told a separate press conference in Nuremberg on Monday that a video was found in the attacker's mobile phone. In the video, the attacker referred to Abu Bakr al-Baghdadi, the leader of the Islamic State.
