What happens when a timing belt breaks on an interference engine?

What causes timing belt to break?
The tensioner that keeps the belt taut is pressurized by the engine oil. If the tensioner has no oil pressure, the belt will become loose and possibly disengage from the pulleys and/or break. If the camshafts don’t have enough oil pressure to operate properly, they will also lock up, causing the timing belt to break.
