Smoke billows in the town of Douma, the last opposition holdout in Syria's Eastern Ghouta, on April 7, 2018, after Syrian regime troops resumed a military blitz to pressure rebels to withdraw. Backed up by Russia's firepower, Syrian President Bashar al-Assad has ousted his armed opponents from nearly all of Ghouta, their last stronghold on the edge of the capital. The regime has used a combination of a fierce military onslaught and two negotiated withdrawals to empty out 95 percent of the enclave, but rebels are still entrenched in its largest town of Douma. / AFP PHOTO / STRINGER
