Just over a year after Trump's air-strikes on an Assad regime airbase in response to the Khan Sheikhoun chemical attack, we've witnessed a repeat of this episode—although this time the air-strikes were on wider targets, and carried out in conjunction with British and French forces. In response to last week's chemical attack on Douma in Syria's besieged Eastern Ghouta enclave, missiles and warplanes from the USS Donald Cook in the eastern Mediterranean carried out the first Western strikes on targets around the Damascus area. The following targets are reported to have been hit: the Damascus Scientific Research Center, said to be linked to production of chemical and biological weapons; another purported chemical weapons lab in Barzeh; a chemical weapons storage facility west of Homs; and headquarters of various elite military units. Iranian forces were apparently also targeted, with a base used by the Republican Guard struck. However, this military action looks like it will be no more sustained than that of last April. Defense Secretary Jim Mattis called it a "single shot," and is believed to have put the brakes on the scope "to keep this from escalating." He told reporters after the initial sorties: "Right now we have no additional attacks planned." There are no reports of any deaths in the air-strikes, and the few known casualties are all military personnel. (American Military News, Middle East Eye, Reuters, NYT, CNBC, BBC News)

UN Secretary-General António Guterres issued a statement April 9 saying he is "deeply concerned" about ongoing air-strikes on Douma in Syria's besieged Eastern Ghouta enclave, noting the "killing of civilians" and "destruction of civilian infrastructure," including hospitals and health facilities. The statement said he is "particularly alarmed by allegations that chemical weapons have been used against civilian populations in Douma." It also noted reports of civilians killed by shelling of Damascus from rebel positions in Douma. Guterres called on all sides to abide by Security Council Resolutions 2401, which last month demanded a 30-day halt to hostilitiess. He reiterated that there is no military solution to the conflict.

Estimates of the dead vary from 70 to 150 after the latest and worst chemical attack on the besieged enclave of Eastern Ghouta, in the Damascus suburbs. The number is likely to rise, as rescue workers are still reporting new casualties following the gassing at the town of Douma, the last in the enclave that remains in rebel hands. The White Helmets volunteer civil defense group said on Twitter: "More families were found suffocated in their houses and shelters in #Douma. The number of victıms is increasing dramatically, and the ambulance teams and the @SyriaCivilDefe volunteers continue their search and rescue operations." The apparent strike by a "barrel bomb" filled with either sarin or chlorine gas targeted a building where displaced families were sheltering from the ongoing air-raids on Douma.

Russian-backed Assad regime forces are on the verge of taking the last remaining rebel stronghold in Syria's Eastern Ghouta enclave, in the Damascus suburbs. A Russian military commander boasted: "The militants are being evacuated from Douma, their last bastion in Eastern Ghouta, and within a few days the humanitarian operation in Eastern Ghouta must be completed." This "humanitarian operation" has seen the near-total destruction of Ghouta by aerial bombardment over the past weeks, with some 1,500 killed. Thousands of fighters and residents have been allowed to evacuate via buses to Idlib, Syria's last rebel-held province, under what was reported as a "surrender agreement."

Turkish forces and allied Syrian rebels announced March 18 that they have seized "full control" of Afrin, following a two-month offensive against the Kurdish YPG militia in the northern Syrian town and surrounding enclave. One of the three "cantons" that make up the Kurdish autonomous zone of Rojava has now been lost. The statement announcing the seizure of the enclave was published on the Twitter page of "Operation Olive Branch," as the offensive was officially dubbed. Once "Olive Branch" forces actually penetrated Afrin town, the YPG apparently withdraw to prevent the civilian population from being caught in the fighting. In the prelude to the town's fall, residents described chaos as fleeing civilians were trapped by artillery and by Turkish air-strikes. The "Nothern Brigade" of the Free Syrian Army was named as the key ground force taking control of the enclave under Turkish direction and protection. (NYT, Syria Direct) Turkey's official Anadolu Agency also names Syrian Turkmen militia forces as involved in taking the enclave, and explicitly appeals to ethnic resentment, stating: "Arab tribes welcome liberation of Afrin."

The UN Commission of Inquiry on Syria released a report (PDF) March 15 condemning the pervasive sexual and gender-based violence that has occurred over the past seven years in the Syrian conflict. The report, entitled "I Lost My Dignity: Sexual and gender-based violence in the Syrian Arab Republic," was written after UN workers interviewed more than 450 survivors, lawyers, healthcare practitioners and other affected individuals concerning the use of such violence between March 2011 and December 2017. The report details the systemic rape, torture, and other acts of sexual violence perpetrated by government forces and affiliated militias at checkpoints, in detention centers, and during interrogations.

A few hundred of the several hundreds of thousands trapped in besieged Eastern Ghouta have been allowed to evacuate to rebel-held Idlib governorate through a "humanitarian corridor" supposedly free of regime and Russian air-strikes. The Assad regime and its allies have now managed to split the enclave into three blocs, each surrounded and under bombardment. Aid groups warn that conditions in the enclave surpass even those seen during the 2016 Aleppo crisis. Ghouta's fall looks increasingly certain, leaving Idlib  as the last rebel-held pocket of Syria. (Middle East Eye, NYT)

Medical facilities supported by Doctors Without Borders (MSF) in the besieged enclave of Eastern Ghouta report having received 1,000 dead and upwards of 4,800 wounded over the two-week period ending March 4. This figure is an underestimate, as it does not include information from all medical facilities supported by MSF in the area, or from facilities not supported by MSF. Warplanes of the Assad regime and its Russian allies continue their apparent intentional targeting of hospitals; 15 out of 20 facilities supported by MSF in East Ghouta have been hit by bombing or shelling during the recent escalation.
