Russia’s Defense Ministry has reported that a Russian major general was killed in eastern Syria’s Deir ez-Zor province on Tuesday after the convoy he was riding in hit an improvised explosive device (IED).

According to the state-owned news agency TASS, the Russian convoy was returning from what the Russian military said was a “humanitarian mission” when it was hit by the IED. Two other Russian officers were wounded. The general was only identified as a “senior military advisor.” He died from his wounds after being evacuated, the ministry added. 

The IED attack reportedly took place near the At-Taim oil field, about 15 km outside the city of Deir ez-Zor, an area that has seen frequent violence. 

The Ministry of Defense said the IED involved was placed on the side of the road along which the Russian convoy was traveling. No one has yet acknowledged responsibility for the latest attack on Russian troops.
