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.

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. 

UN High Commissioner for Human Rights Zeid Ra'ad Al Hussein on March 2 warned Syria that air-strikes, shelling and use of toxic agents in Eastern Ghouta likely constitute war crimes. Zeid asserts that the citizens of Eastern Ghouta are enduring every kind of deprivation, with no aid getting through since November, except for one single convoy of humanitarian aid that managed to reach just 7,200 people, of the hundreds of thousands in the area. "As a direct result, thousands upon thousands of children in Eastern Ghouta are acutely malnourished and profoundly traumatized. And now they are facing one of the most pitiless onslaughts in this long-running and brutal civil war."

A child died and at least 13 other people suffered breathing difficulties after an apparent chemical attack on the besieged Syrian rebel enclave of Eastern Ghouta Feb. 25, medics and monitors reported. The UK-based Syrian Observatory for Human Rights said 14 civilians had suffered breathing difficulties after regime air-strikes struck the village of al-Shifuniyah. One woman is said to remain in a critical condition. A doctor who treated those affected, told AFP he suspected “chemical weapons, probably a chlorine gas attack." (Japan Times)

This is a political tragedy, and bodes more poorly than ever for any eventual return of peace to Syria. This week, Assad regime forces joined the Kurdish militia defending the northern enclave of Afrin from Turkish aggression. The People's Protection Units (YPG), military force of the Kurds' Rojava autonomous region, confirmed in a Feb. 20 statement that after days of negotiations the "Syrian government" and allied forces had entered Afrin. "After more than a month of the legendary resistance of our forces against the Turkish invasion army and the terrorist groups aligned with it from Jabhat al-Nusra, Da'esh and others, and causing severe losses for the invaders... our units considered to call the Syrian govt and its army to undertake its duties in participating in defending Afrin and protecting the Syrian borders against this evil invasion," YPG spokesperson Nouri Mahmoud said. "The Syrian government has thus heeded the call...and sent military units...to concentrate on the borders and participate in defending the unity of Syrian lands and its borders." (The Region)
