Kujtim Fejzulai believed to have acted alone but known to have been an Isis sympathiser

Austrian police are investigating whether an Islamist terrorist who killed four people in Vienna on Monday night was part of a wider network and if the attack could have been prevented.

Kujtim Fejzulai, known to authorities as a sympathiser of the Islamic State group, which claimed credit for the murders, is believed to have been the lone gunman in the attack despite hours of uncertainty over whether accomplices remained at large.

Kujtim Fejzulai deceived mentors in deradicalisation programme, minister says

An Islamic State-supporting gunman who killed four people and injured 23 others in an attack in central Vienna on Monday night deliberately “deceived” his mentors in a deradicalisation programme to feign a renunciation of jihadism, Austria’s interior minister has said.

The 20-year-old dual Austrian and North Macedonian citizen, named as Kujtim Fejzulai, was shot dead by police nine minutes after opening fire in the Austrian capital’s first district at 8pm.

Fact that Isis attacks have declined in EU does not mean threat has disappeared, says expert

Does the attack in Vienna on Monday night presage a return to the darkest days of the wave of terrorist violence that shook Europe between 2012 and 2017?

Over that five-year period, hundreds died in lethal stabbings, attacks with cleavers, bombings of stadiums and airports, as well as assaults by multiple gunmen in city centres with AK-47s that bear horrible resemblance both to that still being investigated in the Austrian capital and the spate of attacks in France in recent weeks.
