Belarusian anti-government activists have claimed responsibility for what they said was a drone attack on a Russian A-50 surveillance aircraft at an airfield near the Belarus capital of Minsk on Sunday. "Those were drones. The participants of the operation are Belarusian," Aliaksandr Azarov, leader of Belarusian anti-government organization BYPOL, was quoted as saying on the organisation's Telegram messaging app and on the Poland-based Belsat news channel. "They are now safe, outside the country."
