At least two civilians were killed and more than a dozen injured during a terror attack from several locations in Vienna, Austria, on Monday.

One suspect also was shot and killed by Austrian police. At least one attacker is still on the run. 

The Austrian Police tweeted that multiple suspects armed with rifles started shooting at 8 p.m. local time in six different locations. 

Counterterrorism sources told Fox News that having shooters in six different locations indicates a coordinated, planned effort.

The Vienna Mayor Michael Ludwig told broadcaster ORF that two civilians have died, according to Reuters.  A woman wounded in an attack died of her injuries, bringing the civilian death toll to two.

Karl Nehammer, Austrian minister of the interior, reported multiple deaths but did not give a specific number. Another official later clarified that was not accurate.

He urged the public to stay away from central Vienna, Reuters reported. The City of Vienna tweeted that “there will be no compulsory schooling in Vienna tomorrow.”

 “It is the hardest day for Austria in many years. We are dealing with a terror attack the severity of which, thank God, we have not experienced in Austria in many years,” Nehammer said at the news conference.

The army is guarding key locations to free up police to search for the gunmen, Nehammer told public broadcaster ORF.

“Our police will take decisive action against the perpetrators of this hideous terrorist attack,” Sebastian Kurz, the chancellor of Austria, tweeted

“I am glad that our police officers have already been able to eliminate a perpetrator. We will never allow ourselves to be intimidated by terrorism and will fight these attacks resolutely by all means.”

Oskar Deutsch, a leader of the Jewish community in Vienna, said that the shooting in Seitenstettengasse took place near a synagogue. 

“It cannot be said at the moment whether the city temple was one of the goals,” Deutsch tweeted. “What is certain, however, is that both the synagogue in Seitenstettengasse and the office building at the same address were no longer in operation and closed at the time of the first shots.”

Rabbi Schlomo Hofmeister said he saw the attackers shooting at people in cafes and bars on the street. 

“They were shooting at least 100 rounds just outside our building,” Hofmeister said. “As of midnight, all bars and restaurants will be closed in Austria for the next month, and a lot of people probably wanted to use that evening to be able to go out.”

European leaders condemned the terrorist attacks Monday. 

French President Emmanuel Macron tweeted that France shares “the shock and sadness of the Austrians after an attack in Vienna.”

Italian Prime Minister Giuseppe Conte tweeted “there must be no place for hatred and violence in our common European house.”
