Prosecutors say the death toll in the attack on a Christmas market in the German city of Magdeburg last month has risen to six as a woman succumbed to her injuries.

The suspect in the car-ramming incident at a Christmas market in the German city of Magdeburg had appeared in seven investigative proceedings in the two years prior to the attack, Germany's Frankfurter Allgemeine Zeitung newspaper reported on Saturday.

In Berlin in 2016, Anis Amri, a failed Tunisian asylum seeker with Islamist links, plowed a truck through a crowded market, killing 12 people and injuring nearly 60 people. Among those killed was a truck driver from whom Amri stole the vehicle, according to German broadcaster DW .
