Vienna terror suspects arrested, 1 dead

At this time, authorities suspect there might be more assailants at large and have deployed a force of 1,000 responders in a manhunt for additional attackers, according to CBS News.

The downed attacker, identified as Kujtim Fejzulai, was a 20-year old duel citizen of Austria and North Macedonia. Authorities say they have found evidence that he had identified as an "ISIS sympathizer," citing his 2019 arrest for attempting to travel to Syria and join the Islamic State. At this time, authorities have not released the identities of the other two suspects, who remain in custody.

Karl Nehammer, Interior Minister for Vienna, said that several additional suspects had been detained and that as many as 15 properties had been searched, but that suspects were still at large.

"According to what we currently know, there is at least one attacker who is still on the run," Nehammer said. "At the moment we can't rule out that there are still other attackers out there. It was unclear how many assailants were involved in the assault."

Sebastian Kurz, Chancellor of Austria, addressed the nation, calling the attack a "repulsive terror attack."

"Yesterday's attack was clearly an Islamic terror attack," the Chancellor said. "It was an attack out of hatred — hatred for our fundamental values, hatred for our way of life, hatred for our democracy in which all people have equal rights and dignity."

The attack, which targetted six different locations in the Austrian capital, left four people dead and as many as 15 others hospitalized. Many sustained bullet wounds and a few are suffering from knife punctures and lacerations. Seven individuals are in critical condition.
