Security operatives nab 14 over Vienna murder in Austria

Austrian police have carried out a series of raids and made 14 arrests after a gunman murdered four people in the heart of Vienna on Monday.

The man, described as a 20-year-old Islamist terrorist who had been freed from jail last December, was shot dead by police as he fired on passers-by.

Security has been tight in the Austrian capital as police launched a manhunt for any further attackers.

Austrian chancellor Sebastian Kurz said the gunman may have acted alone.

He further stated that there is no backing down from the fight against terrorism and its ideology.

The Islamic State (IS) group claimed in a video on its online propaganda channel that it was behind the attacks, without providing any evidence.

The attacks on Monday took place opposite the main synagogue in a pedestrian alley called Seitenstettengasse, and continued until the gunman was shot dead at 20:09.

Police identified a total of six crime scenes in the area.
