During the Syrian Civil War, Douma has been a major flashpoint and witnessed numerous demonstrations against the Syrian government and armed clashes against the Syrian Army and Security forces during the early stages of the conflict. On 30 January 2012, the Syrian Army gained control of the city after the Battle of Douma, a major operation against the opposition armed groups in Rif Dimashq Governorate. On 29 June 2012, the Syrian Army was accused of committing a massacre in Douma, where more than 50 people were killed. As of 18 October 2012, the Free Syrian Army was in control of most of the suburb. Fighting and bombardments continued in the town. Douma is the main city of the Siege of Eastern Ghouta, begun in April 2013, isolating 400,000 people in a 100 square kilometre area. UN and Red Cross aid convoys were able to reach Douma with food and supplies once in 2018. In the 2015 Douma market massacre, the city was attacked by Syrian Army ground-to-ground missiles, leaving at least 50 dead and several more missing. In early 2018, the main rebel faction based in the city was Saudi Arabian-backed Jaysh al-Islam, with an estimated 10-15,000 fighters in the region. On 7 April 2018, a chemical attack was carried out in the city. Douma had been the target of four reported chemical attacks over four months in 2018, as pro-government forces intensified their aerial bombardment before launching a ground offensive. The last - and deadliest, according to medics and rescue workers occurred when a yellow industrial gas cylinder was reportedly dropped onto the balcony of a block of flats. The opposition's surrender came a day later. In September 2018 the UN Commission of Enquiry on Syria reported: "Throughout 7 April, numerous aerial attacks were carried out in Douma, striking various residential areas. A vast body of evidence collected by the Commission suggests that, at approximately 7.30 p.m., a gas cylinder containing a chlorine payload delivered by helicopter struck a multi-storey residential apartment building located approximately 100 metres south-west of Shohada square. The Commission received information on the death of at least 49 individuals, and the wounding of up to 650 others... the Commission cannot make yet any conclusions concerning the exact causes of death, in particular on whether another agent was used in addition to chlorine that may have caused or contributed to deaths and injuries" Local rebels and civilians were sent into northern Syria in forced exile. Similar forced displacement deals have taken place all over Syria.
