RABAT, Morocco (AP) — Morocco's Royal Prosecutor says excessive speed caused the fatal derailment of a passenger train and the driver has been arrested.

Eight people died and more than 80 were injured when the shuttle between Rabat and a coastal town to the north went off the tracks a week ago.

The prosecutor put the blame on the driver Tuesday, saying the train was traveling at 158 kilometers per hour (98 miles per hour), about twice the speed limit, before the accident.

No reasons for the speeding have been given. The driver is in custody and faces homicide and other charges.

The train wreckage has been cleared and service on the line partially resumed.
