A monitor of Syria’s war said Saturday opposition forces now controlled a majority of Aleppo city, reporting Russian airstrikes on parts of Syria’s second city for the first time since 2016.

“Hayat Tahrir al-Sham (HTS) and allied factions... took control of most of the city and government centers and prisons,” said the Britain-based Syrian Observatory for Human Rights, adding that overnight, Russian “warplanes launched raids on areas of Aleppo city for the first time since 2016.”
