Members of Islamist Syrian opposition group Ahrar al-Sham in the northern Raqqa province Fierce fighting raged Friday in a town near the Syrian capital that a UN team visited this week to probe deadly gas attacks that allegedly took place there, monitors said .
\"Violent fighting is pitting regular armed forces against rebels on the northern and western fronts of Moadamiyet al-Sham,\" the Britain-based Syrian Observatory for Human Rights said.
\"The army is trying to advance into the town,\" it said, adding that an air raid and a surface-to-surface missile launched by the army had targeted the area southwest of Damascus.
Moadamiyet al-Sham is one of the places allegedly hit by chemical attacks on August 21 that the opposition say killed hundreds, and UN inspectors who are currently probing if the incident actually took place visited the town on Monday.
According to the Observatory, the town was hit by more than 10 air raids and hundreds of missiles and rockets on the day of the alleged gas attack.
Western states blame the regime of Bashar al-Assad for the attack, which also allegedly hit the Eastern Ghouta area near Damascus, but his government strenuously denies any involvement.
The army has for months been trying to take Moadamiyet al-Sham and Daraya - another Damascus suburb - back from the rebels, without success.
According to Damascus-based anti-regime activist Ibrahim Shaiban, these two rebel strongholds have been \"intensely\" bombed since Thursday.
\"Regime forces have also dispatched men and tanks as back-up,\" he said.
Broadcaster Shaam News Network (SNN) also reported government shelling in Qaboun, Jobar, Barza, and Yarmouk refugee camp, on the outskirts of Damascus.
Further bombardment was reported in Tabaqa, Raqqa governorate, where forces shelled properties near the military airport.
Dozens of citizens were reportedly killed in the village of Shoghour, Idlib, whilst explosive barrels firing was reported in the city of Deir Ezzor.
Activists on the ground in the governorate of Suwayda said rebel fighters clashes with soldiers close to the Khalkhal airport.
