BEIRUT, LEBANON (5:50 P.M.) – On Wednesday, Islamic State forces in western Deir Ezzor province launched a powerful assault against government defenses around the Euphrates city of Al-Mayadeen.
The battle that ensued lasted an entire day with Syrian pro-government forces being able to repel the ISIS operation aimed at recapturing its former self-proclaimed capital city (after it was moved from Raqqa).
According to military-affiliated sources, pro-government groups involved in the operation included the Syrian Army, the all-Palestinian Al-Quds Brigade (also called Liwa al-Quds) and units from the National Defence Forces.
Islamic State fighters took advantage of a dust-storm sweeping across Deir Ezzor, hoping to attack the Syrian Army and its allies without having their operation hindered by airstrikes from Syrian and Russian warplanes.
In the event, pro-government forces were able to turn back the jihadist onslaught even though they had very limited tactical air support.
