U.S. forces killed scores of Russian mercenaries in Syria last week in what may be the deadliest clash between citizens of the former foes since the Cold War, according to one U.S. official and three Russians familiar with the matter.
The Russian assault may have been a rogue operation, underscoring the complexity of a conflict that started as a domestic crackdown only to morph into a proxy war involving Islamic extremists, stateless Kurds and regional powers Iran, Turkey and now Israel.
The U.S., which has advisers stationed at the base alongside Syrian Democratic Forces troops, responded with aircraft and artillery fire.
Yury Barmin, a Middle East analyst at the Russian International Affairs Council, a think tank set up by the Kremlin, said Russia supports Assad’s efforts to reclaim the “crucial” eastern region of Deir Ezzor to help fund his national reconstruction and reconciliation plan, which the U.S. opposes.
On Tuesday, Energy Minister Alexander Novak told reporters in Moscow that Russian companies are interested in contracts to help refurbish damaged oil pipelines and wells.
