Airport; Human Factors
During pushback from gate in ZZZ; the tug suddenly stopped; causing [a] small bump to the airplane. Fortunately; no one was injured; however; the reason for the stop was due to a ZZZ Airport Operations vehicle crossing dangerously close behind us during the pushback. Because of the quick stop; the nose gear pin sheared and Maintenance was called to do an inspection of the nose gear. No damage was found by Maintenance.
A320 Captain reported the tow bar pin sheared during pushback due to the tug suddenly stopping.
