A heroic Syrian food delivery driver who stopped a brutal attack in Austria is now fearing for his life after receiving death threats online. The 23-year-old attacker, identified as Ahmad G, stabbed five people, killing a 14-year-old boy. Alaaeddin Alhalabi, the delivery driver, witnessed the attack and drove his car towards the attacker, flinging him off the vehicle. Alhalabi has received death threats and is afraid for the safety of his wife and three children. The attack in Austria was confirmed to be an 'Islamic attack with IS connections' by the country's Interior Minister.
