“For weeks, Syrian troops, backed by Russian air force, have been advancing in rebel territory as the cease-fire deal reached in 2018 unraveled. The offensive has displaced over half a million people, many of them arriving in open air and temporary shelters, often near the borders with Turkey. Idlib and nearby rural Aleppo are the last rebel-held areas in Syria and are home to more than 3 million people, most of them already displaced by previous rounds of violence.”
