This was announced by the command of the aerospace defense of North America (NORAD).

“On two separate occasions over the past two days, Russian surveillance aircraft have been spotted, tracked and identified in the NORAD region near Alaska entering and operating inside the Alaska Air Defense Identification Zone,” the Twitter post reads.

The agency noted that Russian aircraft did not cross the air borders of the United States and Canada.

Earlier, US presidential envoy for nuclear non-proliferation Adam Sheinman announced Washington's readiness for a dialogue with Moscow on arms control.

Prior to this, US President Joe Biden said that his administration is ready to discuss with Russia a new arms control system that will replace the START III treaty, which expires in 2026.

At the same time, the Kremlin noted that Moscow had not received proposals from Washington on negotiations on the START III treaty.
