Syrian troops have recaptured the sole road into the government-held side of second city Aleppo from Islamic State group fighters who had severed the route, state media reported on Wednesday.

"Our army units have gained full control of the Aleppo-Khanasser-Ithriya-Al-Salmiyeh road after eliminating a number of Daesh (IS) terrorists and it will be open for citizens from tomorrow morning," state television said.
