Austrian city in shock after deadly knife attack

Now to Austria where a 14-year-old boy was killed and 5 people were injured in a stabbing attack in the city of Villach on Saturday.

The attacker, a 23-year-old Syrian national, was apprehended at the scene.

Authorities have identified the incident as an Islamist attack, and said the suspect had sworn allegiance to the Islamic State.

A local food delivery driver's swift intervention by using his vehicle to impede the attacker, likely prevented further casualties.

The attack follows a series of similar incidents in Europe, and has intensified discussions on immigration and security policies within the country.
