Syrian rebels have reportedly breached the city of Aleppo itself, according to open-source analysts and the Syrian Observatory for Human Rights, as thousands of rebel fighters make stunning advances in a surprise offensive against President Bashar al-Assad’s regime in northwestern Syria.
Videos circulating online show rebels on the outskirts of Aleppo, Syria’s second largest city. Three days ago the rebels launched a major offensive and since then they have been moving rapidly towards Aleppo, taking parts of the countryside and towns.

The Syrian Observatory for Human Rights has reported heavy fighting between regime forces and rebels, led by the jihadist group Hayat Tahrir al-Sham (HTS), which controls rebel resistance in neighboring Idlib province.
