(CNN) A vehicle was intentionally driven Friday into three students outside a high school near the southern French city of Toulouse, injuring them, the country's interior ministry said.

A driver was arrested after the collision, and the Toulouse prosecutor has been called to investigate, the ministry said.

The vehicle accelerated as the students crossed a road, the interior ministry said.
