Teenager dead and four injured in knife attack in the city of Villach

A knife attack occurred in the southern Austrian city of Villach on Saturday, leaving one teenager dead and at least four other people wounded. The suspect, identified as a 23-year-old Syrian national, was apprehended by police in the aftermath of the incident.

The victim was a 14-year-old teenager, police spokesman Rainer Dionisio told AFP. The motive behind the attack was not immediately clear, and the investigation is still ongoing.

"A man randomly attacked passers-by with a knife," the spokesman said.

Two of the four people injured received serious wounds, with the others suffering light injuries, Austrian national broadcaster ORF reported. The attack was apparently interrupted by a delivery worker who drove his vehicle at the suspect, preventing further harm, police told the outlet. The authorities have not ruled out the possibility that a second perpetrator may have been involved.

According to media reports, citing eyewitnesses, the suspect shouted "Allahu Akbar" during the rampage.

Unverified imagery circulating online purports to show the man confronted by an armed policewoman. He appears to be smiling in the aftermath of the attack while raising the index finger of his right hand. The gesture, which refers to the Muslim affirmation of faith, has been widely used by Islamic radicals, including Islamic State (IS, formerly ISIS) terrorists.

The attack comes just two days after a car-ramming attack against a trade union demonstration in Munich in neighboring Germany.

A toddler and her mother died Saturday from injuries sustained in that assault, which left 37 others hurt.

An Afghan asylum seeker was arrested on suspicion of deliberately ploughing through the crowd. Police said he may have been driven by hardline Islamist motives.
