An Egyptian Air Force Ilyushin Il-76MF (reg. SU-BTX) left Batajnica Air Base, near Belgrade, Serbia, this morning to return to Egypt.
There have been several such flights between Egypt and Serbia in last months.
The reason for these flights is unknown but it is highly likely that they are arms deliveries.
Reports had leaked in 2021 that Egypt was in negotiations with Serbia for the acquisition of an upgraded version of the 2K12M2 Kub
