A 45-year-old Austrian and a 57-year-old German died in the BMW SUV blast on Saturday, APA said, citing Austrian police investigation. The Austrian man was sitting in the driver's seat and the German guy was in the passenger seat, while a hand grenade was detonated, police said. Both the victims have no criminal record.
