In a fresh sign of its deteriorating relationship with Washington, Russia plans to limit the number of air bases the U.S. can use to launch reconnaissance flights under the Open Skies Treaty.
The restrictions will be introduced Monday in response to U.S. measures to limit Russian military flights in its airspace, said Georgiy Borisenko, head of the Foreign Ministry's North American department, according to the state-run RIA Novosti news agency.
The move is a rollback of an agreement in place since 1992, one of a series of arms control deals intended to foster trust and transparency as the relationship between the nuclear superpowers thawed at the end of the Cold War.
