Russian and Syrian warplanes have intensified attacks on rebels who over-ran most of Aleppo, Syria’s second city, in a lightning assault that poses the biggest challenge in years to Bashar al-Assad’s regime.
Air raids struck the rebel-held city of Idlib for a second day on Sunday, as opposition media and war monitors also claimed that Russian and Syrian jets had launched attacks near Aleppo University Hospital.
Thousands of rebels, led by Islamist group Hayat Tahrir al-Sham, entered Aleppo city, which has a population of 2mn, on Friday. Images circulating on opposition-linked social media this weekend showed them raising their flag over the city’s citadel and posing in its airport.
