More than 100 buses entered Douma Sunday night, after the town came under alleged chemical attack, to transport Jaysh al-Islam rebel fighters and their families out of the East Ghouta town near Damascus. This was reported by Syrian state media. The group also agreed to give up its prisoners in return for an Assad government’s consent to a three-day ceasefire. Jaysh al-Islamic could not be reached for comment. Human rights groups and UN officials said the deal amounted to to forced displacement, a war crime. The U.N. Security Council planned to hold an emergency meeting Monday to discuss the chemical attack.
