On 7 April, Yugoslav bombers of British-design launched raids on Hungarian airfields and railway stations. One of the targets was an airfield near Szeged, but when the Yugoslav aircraft found it empty, they dropped their bombs on the railway network. Another formation attacked airfields used by the Hungarian Air Force around Pécs. Both bomber formations were almost completely destroyed by German fighter aircraft and Hungarian anti-aircraft fire. A rumour spread that British aircraft had been involved in these raids, but this was a false report, probably generated by those in the Hungarian military who wanted Hungary to join in the German campaign. Bárdossy lodged a strong protest with the British regarding the supposed British attack.
