On 18 June 2017, under Operation Laylat al-Qadr (Persian: عملیات لیلةالقدر), Iran's Islamic Revolutionary Guard Corps (IRGC) fired six surface-to-surface mid-range ballistic missile from domestic bases targeting ISIL forces in the Syrian Deir ez-Zor Governorate in response to the terrorist attacks in Tehran earlier that month. Next day, the IRGC published aerial videos recorded by the Damascus-based IRGC drones flying over the city during the operation, confirming that the missiles had successfully hit the targets with precision.
