Turkey has shut its airspace to Russian civil and military aircraft carrying troops from Russia to Syria, a ban that will be effective for three months.
The move is said to add to the growing external pressure on Russia following its Ukraine offensive and could increase the cost of the war for Russia.
However, there is no clarity on whether the decision aims to bar the possible movement of Syrian fighters to Ukraine.
It is said to be the first time that Turkish airspace has blocked Russian aircraft since Russia intervened in Syria’s civil war in 2015.
