The attack is taking place on a busy road in the city of Aafes in northwestern Tunisia, but it was sparked by a misunderstanding.
The parking lot at the Aafs gas station was full and the driver of a passenger car decided to wait in the lot.
When he got out, he noticed that the parking space was empty.
He opened the door and noticed that there was no car parked.
He then pulled out his gun and shot the driver.
He was killed in the ensuing chaos.
