Jihadis and their Turkish-backed allies breached Syria's second city of Aleppo on Friday, as they pressed a lightning offensive against forces of the Iranian- and Russian-backed government.

The offensive began on Wednesday, the same day that a fragile ceasefire took effect in neighboring Lebanon between Israel and Iran-backed militant group Hezbollah.
