Syrian state media and an opposition activist group are reporting that government forces are advancing near the northern city of Aleppo in an attempt to impose a siege on rebel-held parts of the city.
Sunday's push comes a month after insurgent groups captured several military academies south of Aleppo and opened a corridor into rebel-held parts of Syria's largest city and former commercial center.
Since then government forces and their allies have been trying to recapture the area.
State news agency SANA quoted an unnamed military official as saying that troops have captured the Armament Academy and are "continuing their advance in the area to impose almost a total siege on the gunmen in Aleppo."
The Britain-based Syrian Observatory for Human Rights confirmed that government troops captured the academy.
