Russia sortied Tu-22 M3 ‘Backfire’ strategic bombers and Su-34 ‘Fullback’ fighter-bombers from the base, claiming to conduct airstrikes against alleged Islamic State targets in Deir e-Zor Province as well as Jabhat Fateh a-Sham (formerly Jabhat a-Nusra) targets in Aleppo and Idlib Provinces. And the U.S.-backed Syrian Democratic Forces (SDF) – a coalition consisting of the Syrian Kurdish YPG and allied opposition groups – seized full control over Manbij after clearing the Islamic State from the last remaining districts of the city center.

The campaign began on May 31.  Read this SITREP in full here.
