Russia’s airplanes cut off routes used by Islamic State (IS, formerly ISIS/ISIL) to deliver supplies to Syria from Iraq by bombing a bridge over the Euphrates River, the Russian General Staff said.

“The bridge over the Euphrates River near [the Syrian city of] Deir ez-Zor was a key point of the logistics chain [of IS]. Today Russian pilots carried out a surgical strike against the object,” the deputy chief of the General Staff of Russia, Colonel General Andrey Kartapolov, said on Thursday during a news briefing, adding that the terrorist group’s armament and ammunition delivery route had been cut off.

Kartapolov also stressed that the strike was delivered in a region that, according to the US military, was fully controlled by IS militants.
