Hi,
Although it does sound like the timing belt broke, you need to pull the top timing belt cover to verify.
One concern of note. This is an interference engine, which means that there is a possibility that the valves were damaged when the belt broke, but if it broke while idling, you have a good chance of no damage. But dont keep cranking engine over until you verify that timing belt is broke or not.
