Germany has not yet received background information from Italian authorities about Anis Amri, the suspect in the Berlin Christmas market attack, a month after he was killed in a shootout close to Milan, Die Welt reported Thursday.

“The answer to current requests to the Italian authorities, among others about the residence permit issued to Anis Amri in Italy, is still pending,” the government said in response to parliamentary questions.

Amri, who drove a truck into a crowd at a Berlin Christmas market December 19, killing 12 people and injured dozens, escaped Berlin in the aftermath of the attack, traveling via the Netherlands and Belgium to Italy, where he was killed by police four days later.

He initially entered Italy in 2011, before traveling to Germany in the summer of 2015.

German authorities had learned Amri intended to carry out terror attacks in the country, but the warnings were too abstract to justify an arrest, Dieter Schürmann, head of North Rhine-Westphalia’s criminal investigative agency, said earlier this month.

MPs from German Chancellor Angela Merkel's Christian-Democrat party (CDU) this week called for an investigative committee into the Amri case, while members of the Social-Democrats, the CDU's junior coalition partner, want an external special envoy.
