Sources said the bus reversed into the Pembroke Park and Ride ditch wall.
It has since been removed.
In a statement, the Malta Public Transport said it was conducting an internal investigation to establish the cause of the accident, which took place this morning at the Pembroke Park and Ride.
Its health and safety officials immediately closed the site of the accident.
