At least twelve people have sustained injuries, with four reportedly in critical condition, after a car rammed into them in the Italian city of Modena.

The driver, described by the media as a “highly intoxicated” man of North African descent, was reportedly armed with a knife, and stabbed a person before being subdued by bystanders.

While the motive remains unclear for the time being, terrorism is not being ruled out, according to Italian newspaper La Pressa.
