DAMASCUS, Aug. 14 (Xinhua) -- The Syrian army reached on Wednesday the outskirts of the Khan Shaykhun town in the countryside of the northwestern Idlib province, a war monitor said.
The army forces reached 4 km west of Khan Shaykhun after capturing several areas in the southern countryside of Idlib, the Syrian Observatory for Human Rights said.
The Britain-based watchdog group said that the government forces are attempting to inch closer to the town's eastern flanks.
It added that over 100 fighters from both sides had been killed since Tuesday amid ongoing airstrikes on rebel-held areas in Idlib.
Meanwhile, state news agency SANA reported that the army succeeded on Wednesday in securing several towns in the southern countryside of Idlib, following battles with the al-Qaida-linked Nusra Front.
On Sunday, the Syrian army captured the key town of al-Habit in the countryside of Idlib Province, a progress that paved the way for capturing more areas in Idlib, the last major rebel stronghold in the country.
The progress enabled the Syrian army to advance toward Khan Shaykhun, which is located 11 km east of al-Habit.
Idlib, as well as the northern countryside of Hama, are included in the de-escalation zones' deal that was reached between Russia and Turkey last September.
The deal, however, has largely failed despite several attempts to revive it.
The latest attempt to fix the deal took place earlier this month when Turkey and Russia mediated a fresh cease-fire in Idlib, which failed quickly with the resumption of the military showdown.
