Germany says no claim of responsibility yet
BERLIN - Germany's top prosecutor says investigators are treating the Berlin Christmas market attack as an act of terrorism, though there is no claim of responsibility yet.
Peter Frank also told reporters Tuesday it's not entirely clear whether there was one perpetrator or more. He says the suspect in custody "may not have been the perpetrator or belong to the group of perpetrators."
Frank says the method used in the rampage was reminiscent of July's truck attack in Nice, France and of the "modus operandi" used by Islamic extremist groups.
German Chancellor Angela Merkel has summoned her top security officials to discuss the government's response to the deadly truck attack in Berlin that claimed at least 12 lives and left nearly 50 injured.
Germany's interior minister says authorities have been questioning a suspect, who was taken into custody after the truck plowed into a busy Christmas market. But they say the man, who's from Pakistan and has applied for asylum, is denying involvement, and now authorities question whether he was the truck driver.
