August 16, Hungary protested that the Yugoslav military had destroyed bridges that
connected the two frontiers, while Tito charged that Bulgaria had sent spies across the
border. On October 1, Romania charged that Yugoslavia had violated their airspace.

diplomats. Later that month Yugoslavia sent notes to Hungary, Rumania, Bulgaria,
and Albania charging them with 227 border violations. On October 26, Bulgarian
