MOSCOW, November 6. /TASS/. A US-registered NATO reconnaissance aircraft flew around Russia’s Kaliningrad Region in circles for more than three hours, a source in air traffic control told TASS.

The source noted that this was the third time the aircraft had been spotted near the Russian exclave since the beginning of the week.

"The Bombardier Artemis II flew clockwise around the Kaliningrad Region for just over three hours, passing through Polish and Lithuanian airspace and over the neutral waters of the Baltic Sea," the source said.

The aircraft had made similar flights on Wednesday and Monday, with those flights lasting between one and four hours, the source added.

"The aircraft is now heading to its home base at the airfield in Constanta, Romania," the source said. It also frequently flies over the southern Black Sea, traveling east and west, as well as over the central Baltic states, turning near Estonia’s coast along the Gulf of Finland, the source added.
