Americans going to Spain for the Olympics, Expo '92 in Seville and other events next year should beware of thieves who break the windows of cars stalled in traffic, according to a travel advisory issued by the State Department.

Observing that Spain has little history of violent crime but does suffer from petty crime in tourist areas, the department says unsuspecting visitors can lose their belongings to bicyclists and motorcyclists but most often to pedestrians.
