Russian Air Force Major Roman Filippov, a pilot of Russia's Su-25, who was killed after his jet had been downed in Syria, has never been a Ukrainian citizen.
"He is a Russian career military who was transferred to Crimea from the Russian Federation and became a member of the 37th mixed aviation regiment (under command of Colonel Oleg Terebunsky)," Ukrainian journalist Yuriy Butusov wrote on Facebook.
"The regiment is based in Hvardiyske in occupied Crimea. The information of the Russian Defense Ministry, spread by the Russian Novaya Gazeta newspaper that Filippov was a former Ukrainian defector, is not true," Butusov said.

"But he chose to be a terrorist and flew to the war in Syria. The Russian air force has mercilessly been bombing the town of Saraqeb and nearby settlements for over a week. For all that time the insurgents could not retaliate against Russian air terrorists," Butusov wrote.
Saraqeb is not occupied by ISIS terrorists, opposite to what the Russian media report, he said. This city has long been under Turkish-backed insurgents' control.
