US officials believe that Iran “resourced and encouraged” an October 20 attack on a military outpost housing US forces in the eastern Syrian desert which involved drones carrying explosive charges and “indirect fire,” possibly rockets.
A local source from Syria’s Deir al-Zor region told Al-Monitor that four drones had been launched on Oct. 20 from what appeared to be a civilian area between 15 and 20 km west of the city of Albu Kamal in Deir al-Zor.
