The B200F engine is, i believe, a borderline engine. Many say it's a non-interference engine but there have been others that have had valve to piston contact. However, in the majority of cases, those people also knew the head had previously been off and skimmed so reducing that vital valve to piston clearance.

Given that you were stopped at the time and hopefully only turned over on the starter, there's a fair chance you have got away with it - only way of being sure is to fit a new timing belt.

Are you sure it's a B200F? Is it mechanical or electronic injection and does it have a Lambda sensor and cat or not? A photo would help if you're not sure. If it's a B200E with K-Jetronic (mechanical) injection, there's a much higher chance of there being no damage.
