Around 10 August 2014, ISIL started to continuously attack Tabqa Airbase. On 17 August, the
Syrian Air Force launched 26 airstrikes on ISIL-held
Raqqa city and around Tabqa, killing at least 31
ISIL fighters and wounding dozens. At least eight civilians were also killed and ten wounded. At the same time the army launched an equal number of airstrikes in Deir Ez-zor against ISIL positions, bringing the total number of airstrikes to 40. The following day the Syrian Air Force launched another 20 airstrikes against ISIS positions, one of which destroyed the Raqqa city water plant, cutting off water supply to the city. According to
Al Rai reporter Elijah J. Magnier, the Syrian Air Force used guided missiles following U.S. intel on ISIS gatherings. According to an anonymous source, the U.S. and an unidentified Western country provided the Syrian military with lists of ISIS targets acquired through drone intelligence. Meanwhile, the Syrian army sent reinforcements to Tabqa Airbase, and strengthened fortifications inside the base. It also supplied its garrison with large quantities of ammunition and food. == Ramped-up fights ==
