|Scores of Russians fighting for Bashar al-Assad died in a failed attack on a base and refinery held by the U.S. and its allies. U.S. officials put the death toll at about 100, with 200 to 300 injured. The Russian assault may have been a rogue operation. Russia’s military said it had nothing to do with the attack and the U.S. military accepted the claim.|
The offensive began about 8 kilometers (5 miles) east of the Euphrates River de-confliction line late on Feb. 7, when adversaries fired rounds and advanced in a “battalion-sized dismounted formation supported by artillery, tanks, multiple-launch rocket systems and mortars” No fatalities were reported on the coalition side.
