On Saturday, the new government’s 23-member cabinet was announced.
Among those announced was Hind Kabawat, a Christian woman and activist who opposed Assad since the conflict began in March 2011, and who will serve as minister for social affairs and labour.
Meanwhile, Mohammed Yosr Bernieh has been named Syria’s finance minister in the new government.
Both Murhaf Abu Qasra and Asaad al Shibani will remain in their roles as defence and foreign ministers, respectively.
They had both served in the previous caretaker government following the fall of the Assad regime.
