The rapid advance on Aleppo came just four days into a surprise rebel offensive that is the most intense escalation in years in the country’s civil war.

By Saturday, they had taken control of "large parts" of the country's second-biggest city, Aleppo. The surprise offensive prompted the first Russian strikes on Aleppo since 2016, and saw Syria's military withdraw its troops from the city.

Islamist rebels breached neighborhoods in Syria’s second-largest city of Aleppo and clashed with government military forces after detonating two car bombs Friday.

Israeli aircraft struck Hezbollah weapons smuggling sites along Syria's border with Lebanon, the Israeli military said Saturday, testing a fragile, days-old ceasefire that has seen continued sporadic fire.
