Commander of an extremist militant group along with 24 of his group members have been arrested in Syria during army’s anti - terrorist operations in the northwestern city of Baniyas.

According to a report, Syrian army soldiers attacked a base belonging to the Fajr al - Islam militant group in Baniyas, arresting 25, among them was the commander of the group.

Operations continued in Aleppo and Idlib with the army advancing step by step, clearing towns and villages from foreign - backed insurgents.

There were also reports of fresh infighting between two groups of insurgents, Dowlat - e Islami and al - Nusra Front in the border town of al - Dana at Idlib suburbs.

The two militant groups have been battling each other in recent month and latest fighting on Tuesday left several of the both sides dead.

Deadly clashes between rival militant and terrorist groups fighting in a foreign - backed insurgency in Syria have been increasing recently, most of them over booty shares.

Meanwhile, civilian volunteer fighters that have set up committees to back the army across Syria, made considerable advancement in Yermouk refugee camp, where Palestinian refugees helped the army battle attacking insurgents.

Syrian soldiers have been advancing apace in their operations throughout the country in recent months.

The war in Syria started in March 2011, when pro - reform protests turned into a massive insurgency following intervention of western and regional states.

The unrest, which took in terrorist groups from across Europe, the Middle East and North Africa, has transpired as one of the bloodiest conflicts in recent history.

As the foreign - backed insurgency in Syria continues without an end in sight, the US government boosts its political and military support to Takfiri extremists.

Washington has remained indifferent about warnings by Russia and other world powers about the consequences of arming militant groups.
