Halle, Oct 9 (AP) A heavily armed assailant tried to force his way into a synagogue Wednesday in eastern Germany on Yom Kippur, Judaism's holiest day, and two people were killed as he fired shots outside the building and into a kebab shop, authorities and witnesses said.

The attacker shot at the door of the synagogue in the city of Halle but did not get in as 70 to 80 people inside were observing the holy day, a local Jewish leader said. Video of the attack was livestreamed on streaming site Twitch, which said it had "worked with urgency" to remove it.

Germany's top security official, Interior Minister Horst Seehofer, said authorities must assume that it was an anti-Semitic attack, and said prosecutors believe there may be a right-wing extremist motive to it. He said several people were injured.

Police said in a tweet early Wednesday afternoon that "the suspected perpetrators" had fled in a car after the attacks and quickly reported that one person had been arrested. Officers spread out in force across Halle, a city of 240,000, urging residents to stay at home.

Several hours later, police said there was no longer an "acute" danger to the city and residents could go back into the streets. They gave no details about the person who had been arrested.

Police also didn't specify why their assessment had changed, but the news agency dpa and the Bild newspaper cited unidentified security sources as saying the evidence points to a lone assailant.

News magazine Der Spiegel, which didn't cite its sources, said the suspect is a 27-year-old man from Saxony-Anhalt state, where Halle is located.

Rita Katz, the head of the SITE Intelligence Group, wrote on Twitter that 35 minutes of footage of the attacks were posted online, and that the attacker said in English before the shooting that the "root of all problems are the Jews."

She said it showed the attacker shooting a woman in the street after failing to enter the synagogue, then entering a business and killing another person before fleeing.

Twitch said it would permanently suspend any account found to be posting or reposting "content of this abhorrent act."

The filming of Wednesday's attack echoed another horrific shooting halfway around the world, when a far-right white supremacist in March killed 51 people at two mosques in Christchurch, New Zealand and livestreamed much of the attack on Facebook. That massacre drew strong criticism of social media giants for not immediately finding and blocking such a violent video.

The attack was the third to target a synagogue in a year, following attacks in the United States on synagogues in Pittsburgh and Poway, California.

Federal prosecutors, who in Germany handle cases involving suspected terrorism or national security, took over the investigation into the attack in Halle.

A video clip broadcast by regional public broadcaster MDR showed a man in a helmet and an olive-colored top getting out of a car and firing four shots from behind the vehicle from a long-barreled gun. It wasn't clear what he was shooting at.

Pictures from the scene showed a body lying in the street behind a police cordon, opposite the synagogue, which was about 30 meters (yards), dpa reported.

The head of Halle's Jewish community, Max Privorozki, told Der Spiegel that a surveillance camera at the entrance of the synagogue showed a person trying to break into the building while there were 70 or 80 people inside.

"The assailant shot several times at the door and also threw several Molotov cocktails, firecrackers or grenades to force his way in," he said. "But the door remained closed — God protected us. The whole thing lasted perhaps five to 10 minutes."

Dpa quoted unidentified security sources as saying that an assailant laid home-made explosives outside the synagogue.

A witness interviewed on n-tv television said he had been in a kebab shop when a man with a helmet and a military jacket threw something that looked like a grenade, which bounced off the doorframe. Conrad Roessler said the man then shot into the shop at least once.

"All the customers next to me ran, of course I did too. I think there were five or six of us in there," Roessler said. "The man behind me probably died." "I hid in the toilet," he said.

"The others looked for the back entrance. I didn't know if there was one. I locked myself quietly in this toilet, and wrote to my family that I love them, and waited for something to happen."

Police then came into the shop, he said.

Synagogues are often protected by police in Germany. Security was stepped up at synagogues in other cities after the shooting in Halle.
