Syrian government forces stormed the town of Khan Sheikhoun yesterday amid fierce clashes with armed opposition groups, leaving dozens dead.
The Syrian Observatory for Human Rights said the government's ground troops penetrated Khan Sheikhoun in Idlib province for the first time since they lost control of it in 2014.
Khan Sheikhoun is the most important city in the southern Idlib countryside as it contains a strategic highway links Aleppo to Damascus. Regime forces have been aiming to take control of it, according to political analysts.
Bashar Assad's forces are trying to advance deeper in Khan Sheikhoun in order to encircle the strategic town from the north and west and to seize the key highway, but they are facing resistance from opposition fighters.
