“Russia places no-fly zone over Ukraine's Donbas region”

The region, which is part of eastern Ukraine, consists of Donnetsk and Luhansk.

They are controlled in part by pro-Russian separatists, who define regions like the Donetsk People's Republic and the Luhansk People's Republic.

Much has been said about restricted travel areas during this conflict, with Ukraine calling on the West to establish an area over its territory.

One forbidden flight zone is a ban on all or certain kinds of aircraft flying through a certain airspace.

Those who establish a no-fly zone should be willing to take down any aircraft that violates space.

The movement could be used to protect targets on the ground, such as civilians fleeing to security.
