A Saudi doctor suspected of killing five people in a rampage at a German Christmas market allegedly threatened to carry out a terror attack two years before he was granted asylum.

Taleb al-Abdulmohsen, who is alleged to be the SUV driver who rammed into a packed festive market on Friday evening in Magdeburg, warned in 2013 that he would carry out a “Boston Marathon-style” terror attack, it is claimed.

Angry that a German medical association had requested more paperwork before allowing him to practise as a psychiatrist, Abdulmohsen threatened the association on the phone with the words: “Did you see what happened in Boston? Something similar will happen here too.”

He made the threat just two days after Islamist terrorists set off two bombs during the Boston Marathon in an attack that killed three people and injured hundreds more.
