"Police in Basra arrested the truck driver who ran over six students, killing them and injuring 14" others in the Al-Hartha region, interior ministry spokesperson Miqdad Miri said.
According to initial information, the driver "lost control of the truck when the brakes failed," he added in a statement.
In 2022, road accidents in Iraq claimed the lives of more than 4,900 people, an average of 13 per day, according to health ministry figures.
Conflict, neglect and endemic corruption have left oil-rich Iraq's infrastructure, including roads and bridges, in disrepair.
Officials often blame crashes on drivers ignoring the speed limit, using mobile phones behind the wheel, and drug and alcohol consumption.
