Hungarian Prime Minister Viktor Orban has called on Brussels to protect Europe’s borders from illegal immigration in the wake of the deadly terrorist attack in Berlin, but European Commission head Jean-Claude Juncker prefers to rely on European values.

Axar.az reports that, “It is unprecedented that, in the heart of Europe, Christians were murdered at Christmas,” Orban said.

A 24-year-old Tunisian, Anis Amri, drove a truck into Christmas market stalls next to Kaiser Wilhelm Memorial Church at Breitscheidplatz in a December 19 terrorist attack that left 12 people dead and 56 others injured.

The Islamic State terror group (IS, formerly ISIS/ISIL) claimed responsibility for the attack and later released a video of the suspect pledging allegiance to their leader.

Amri who applied asylum in Germany was arrested and released in 2015 and was supposed to be deported, but Tunisian authorities refused to take him back.

Unable to go home, Amri went to Germany in July of 2015 and applied for asylum in April of 2016, registering at different refugee centers and using a number of fake names. In July, Amri was caught with fake Italian ID documents in a routine check on a coach in Friedrichshafen. He was then moved to a prison in Ravensburg, but was soon released again.

Orban said that the Berlin attack has once again proved that the integration of non-European migrants into Europe has “obviously been a failure.”
