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.

A 52-year-old woman has died in hospital from injuries sustained in last month's Christmas market attack in Magdeburg, Germany, bringing the death toll to six, prosecutors have announced. The victim succumbed to injuries received when a car was deliberately driven through crowds of shoppers at the festive market on December 20.

Officials say five people have been killed, including a 9-year-old, after a Saudi doctor drove into a Christmas market teeming with holiday shoppers in the German city of Magdeburg on Friday.

At least five people are now known to have been killed in the vehicle-ramming attack on a Christmas market in the German city of Magdeburg on Friday.

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.

German prosecutors are commissioning a detailed mental evaluation of the suspected attacker behind a vehicle rampage through the crowded Magdeburg Christmas market that left five dead and more than 230 injured.
