Polish truck driver may have been killed while trying to stop the attacker

The Polish driver of the hijacked truck which later crashed into a Christmas market in Berlin was found shot dead in the cabin of the vehicle, but media reports said he had been alive until the attack took place. Reports in the German and international press also quoted an investigator as saying there must have been a struggle with the attacker, who may have been injured before the truck rammed into a portion of the market. Police initially arrested a Pakistani asylum-seeker near the scene, but released him without charge on Tuesday. They are now looking for the suspect Anis Amri, a Tunisian national, whose identity documents were found under the truck seat. Amri had entered Germany in 2015 and applied for asylum, but his application had been rejected by the German authorities, press reports stated. Meanwhile, the head of a group of interior ministers from Germany's 16 federal states, Klaus Bouillon, was quoted as saying tougher security measures were being implemented to prevent such attacks in the future. "We want to raise the police presence and strengthen the protection of Christmas markets. We will have more patrols. Officers will have machine guns. We want to make access to markets more difficult, with vehicles parked across them," Bouillon told the media.
