US spy plane flew "dangerously close" to passenger jets near Russian border

A US defense attache has been summoned by Russia's Defense Ministry after an incident over the Sea of Japan near Russia's eastern borders, where an American spy plane was detected flying too close to civilian aircraft. Russia's air defense detected an RC-135 spy plane belonging to US Air Force on Sunday, the ministry said in its statement. The plane was on an air reconnaissance mission with all of its transponders having been shut off, it added. The US crew had not provided any information regarding its flight to air traffic controllers in the region, despite it flying at the same altitude as scheduled civil aviation flights.
