The suspect in the deadly 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, dpa has learned from security sources.

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.

The number of people injured in the attack on a Christmas market in the German city of Magdeburg two weeks ago has risen to 299 from the previously reported 235, the state Interior Ministry said on Friday.

Germany's interior minister said on Monday it was still too soon to jump to any conclusions about the man suspected of driving his car into a Christmas market in Magdeburg and killing at least five people.

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.
