BERLIN

At least four people were killed and 22 more were wounded in a terror attack in the Austrian capital, an official said on Tuesday.

Speaking at a news conference in Vienna, Interior Minister Karl Nehammer said the assailant, who was killed in a police operation last night after the attack, was a sympathizer of the Daesh/ISIS terror group.

“We have not yet found any evidence indicating a second attacker,” he said, adding that the investigation was still ongoing. 

The minister urged people to exercise utmost caution.

Authorities have confirmed that the 20-year-old assailant was known to police, as he was arrested last year for attempting to travel to Syria to join terror group Daesh/ISIS.

Local media identified him as Kujtim F., who had both North Macedonian and Austrian citizenship.

He was released from jail in December due to his young age.

Austrian police arrested 14 suspects on Tuesday after raids to more than a dozen locations across the country./aa
