The bombing of Belgrade was preceded by the commencement of the ground invasion a few hours earlier, and coincided with air attacks on VVKJ airfields and other strategic targets across Yugoslavia.
Pengeboman Beograd didahului oleh penyerbuan darat beberapa jam sebelumnya dan dilakukan bersamaan dengan serangan udara terhadap lapangan udara Angkatan Udara Kerajaan Yugoslavia dan sasaran-sasaran strategis lainnya di Yugoslavia.
