              This satellite image from Maxar Technologies shows a Beriev A-50 early warning aircraft, center, at Machulishchy Air Base near Minsk, Belarus, Tuesday Feb. 28, 2023. Satellite photos taken Tuesday analyzed by The Associated Press appear to show a Beriev A-50 early warning aircraft targeted in a claimed guerrilla attack at a Belarus air base still largely intact. The Associated Press has been unable to independently confirm the claimed attack, which both Belarus and Russia have yet to acknowledge.
