Two people were killed in shooting attacks on a synagogue and a nearby kebab shop in the eastern German city of Halle on Wednesday and one suspect was arrested, but two others fled in a hijacked a car, officials said.
The violence occurred on Yom Kippur, the holiest day of the calendar in Judaism when Jews fast, seeking atonement. Broadcaster n-tv reported that two people were seriously injured in the attack, in addition to the two killed.
The two suspects on the loose headed out on a motorway that leads to Munich in the country's south, according to the mayor of the town of Landsberg, adjacent to Halle. Gunfire was also heard in Landsberg, Focus Online reported.
A spokeswoman for the Halle municipal government said one shooting took place in front of the synagogue on Humboldt street and its accompanying cemetery, while a second burst of gunfire targeted the kebab bistro in the city in the province of Saxony.
Max Privorozki, Halle's Jewish community chairman, described how a gunman tried to shoot his way into the city's synagogue.
"We saw via the camera system at our synagogue that a heavily-armed perpetrator with a steel helmet and a gun tried to shoot open our doors," he told the Stuttgarter Zeitung newspaper. "The man looked like he was from the special forces...But our doors held."
"We barricaded the doors from inside and waited for the police," he said, adding that about 70-80 people were inside the Humboldt street synagogue celebrating Yom Kippur.
German Chancellor Angela Merkel's government voiced outrage over the attack on Yom Kippur and urged tougher action against anti-Semitic violence.
"That on the Day of Atonement a synagogue was shot at hits us in the heart," Foreign Minister Heiko Maas wrote on Twitter. "We must all act against anti-Semitism in our country."
The federal prosecutors office said it had taken over the investigation from local police, a procedural step under German law indicating suspicions of terrorism committed by political extremists.
Anti-Semitism is a particularly sensitive issue in Germany, which during World War Two was responsible for the genocide of 6 million Jews in the Nazi Holocaust. Around 200,000 Jews live today the country of around 83 million people.
Another Halle city spokesman said an emergency situation had been declared and all residents had been advised to stay at home. He said that emergency services and police were evacuating people from the synagogue.
Rifat Tekin, who worked at the kebab outlet, said he was making a kebab for two construction workers when a perpetrator threw an explosive at the restaurant before shooting.
"He was very calm, like a professional," Tekin told n-tv television. "He didn't say anything. He just kept coming and shooting...I was hiding behind the salad counter."
Another witness, Conrad Roesler, said that when the kebab bistro attacker started firing, "I hid in the toilet."
Broadcasters showed images of an alleged perpetrator dressed in combat garb including a helmet.
An unnamed witness told local media the assailant at the synagogue also threw several explosive devices into the cemetery. Regional broadcaster MDR aired images of a man in combat clothing firing shots along a street from behind a car.
"Our forces have detained one person," local police said on Twitter. "Please nonetheless remain vigilant." Earlier, police tweeted: "According to initial findings, two people were killed in Halle. There were several shots."
The identities of the dead and injured were not immediately known.
National rail operator Deutsche Bahn said the main train station in Halle had been closed.
In Berlin, the state interior senator advised police to step up security at Jewish institutions in the German capital.
Despite comprehensive de-Nazification in the post-war era, fears of resurgent anti-Semitic hatred have never completely gone away, whether from fringe, far-right neo-Nazis or more recently from Muslim immigrants.
Occasional past attacks have ranged from the scrawling of Nazi swastikas on gravestones to firebombings at synagogues and even several murders. In recent years, cases of assault or verbal abuse, in some cases directed against people wearing traditional Jewish skullcaps, have raised an outcry.
