Several people have been injured while another has died after an alleged terror shooting near a synagogue in Vienna.
Dozens of police are out in force on the streets of the Austrian capital following reports of gunfire near one of the city’s main squares.
Oskar Deutsch, the head of the Jewish community in Vienna, said the shooting took place in the street where the city's main synagogue is located but that it was not clear whether it had been targeted.
The synagogue was closed at the time of the shooting, Mr Deutsch tweeted.
Austrian news agency APA quoted the country's Interior Ministry as saying one attacker had been killed and another could be on the run.
Interior Minister Karl Nehammer told Austrian broadcaster ORF that the attack is believed to be terror related.
He said: "At the moment I can confirm we believe this is an apparent terror attack.”
Police said the operation in the centre of the city is ongoing and urged people to avoid open spaces and public transport.
"There are several injured persons," police tweeted. "We are on site with all available forces. Please avoid all public squares in the city."
Police added that the circumstances of the incident are still being determined.
Austrian public broadcaster ORF cited witnesses as saying several shots were fired shortly after 8pm local time.
