Aleppo airport closed

Syrian authorities closed Aleppo airport as well as all roads leading into the city on Saturday, three military sources told Reuters, as rebels opposed to President Bashar al-Assad said they had reached the heart of Aleppo.
The opposition fighters, led by the Islamist militant group Hayat Tahrir al-Sham, carried out a surprise sweep through government-held towns this week and reached Aleppo nearly a decade after having been forced out by Assad and his allies.
