A driver rammed a truck into a festive Christmas market in the German capital last night, killing at least 12 people and leaving nearly 50 injured. The German prosecutor leading the investigation believes the apparent attack on the Berlin market indicates a potential Islamist terrorism plot. Angela Merkel herself has admitted the government "assumed" they were dealing with a terror attack.

Officials today revealed that the man detained by the police last night might not be the attacker himself, meaning the attacker could still armed and on the run. And a US counterterrorism expert today said the German Chancellor only has her own policies to blame for the horrific attack. Jim Hanson said Mrs Merkel has been "importing jihadists in massive numbers". In an appearance on Fox News, he said Germany was at higher risk of terror because of the Chancellor's decision to accept waves of migrants from Africa and the Middle East. During the refugee crisis last year, Germany became the beacon for millions of migrants travelling across Europe.

Mrs Merkel herself said there was "no limit" on the number of migrants the country could accept. However, Mr Hanson said the German government was now paying the price for their open borders. He said: "When someone declares war on you, you don't invite them to your country. "Chancellor Merkel has been importing jihadists in massive numbers, more that a million last year alone." The terror expert added that it was extremely dangerous to bring in people from hotbeds of extremism, especially when there was no way to properly vet those arriving.
