The first batch of F-16 fighter jets from NATO allies has arrived in Ukraine, Bloomberg reports.
The last date for the delivery of these aircraft was the end of July. The agency's sources note that the number of fighters is small.
It is unclear whether Ukrainian pilots, who have been training with Western instructors in recent months, will be able to start using the combat aircraft immediately or whether this process will take longer.
The Ministry of Defence has not officially commented on the arrival of the F-16s.
The arrival of the fighter jets in Ukraine has been complicated by various delays, issues with spare parts, and the language barrier between Ukrainian pilots and their foreign instructors.
There is also concern about the lack of runways, and those that do exist are vulnerable to Russian attacks.
