The timing belt is off track. It did not snap.
A timing belt that appears to be slipping its way off its gear, or coming off track, is an indication that the timing belt is loose. When the timing belt starts to slide off its gears, it can rub against stationary objects and cause damage to itself. If this belt breaks, there can be potential for serious engine damage. This is likely what you are experiencing in your Ford Escort. I would recommend enlisting the assistance of a certified mechanic, such as one from YourMechanic, to stop by and go over your Ford with you, diagnose the timing belt properly and see if it needs to be replaced.
