ROME (Reuters) - There is no sign the man suspected of killing 12 people with a truck at a Berlin Christmas market on Dec. 19 had a network in Italy, Prime Minister Paolo Gentiloni said on Thursday.

Asked at a news conference about Anis Amri, the Tunisian suspect who was shot dead in Milan four days after the attack, Gentiloni said, “We have no evidence of particular networks ... that Amri had in Italy.”

Police are investigating whether Amri, who crossed Europe undetected after the attack, was seeking shelter in Italy or trying to reach another country.
