TOPSHOT - Syrian civilians flee on August 21, 2019 a conflict zone in Syria's rebel-held northwestern region of Idlib, where government bombardment has killed hundreds since late April. - Damascus said on August 22 it is opening a corridor for civilians to leave the Idlib province. Damascus has opened such corridors out of other rebel bastions in the past as a prelude to retaking them either by force or through negotiated surrenders. The Idlib region, which sits on the Turkish border, is now the last major stronghold of opposition to the Russia-backed government of President Bashar al-Assad. (Photo by Omar HAJ KADOUR / AFP)
