IDLIB, Syria

Eleven opposition groups fighting against the Bashar al-Assad regime in Syria formed a new alliance in northwestern Idlib province on Monday.

The sources from the groups said they merged under the name of "National Front for Liberation."

“The aim of the new formation is to unite the components of the Free Syrian Army in Idlib province on Syria under one roof,” the new formation said on social media.

The formation includes following groups: Sham Legion, Jaysh al-Nasr, Free Idlib Army, 1st Costal Division, 2nd Costal Division, 1st Division, 2nd Army, Army of Elites, Shuhada al-Islam Darayya, Al-Hurriyat Brigade, and 23rd Division.

All of the groups have been operating in Idlib and northern part of Hama under the Free Syrian Army.

The Sham Legion commander Fadil Allah al-Hajji became the leader of the new front, while Suhaib Layyush from Jaysh al-Nasr was appointed as his deputy.

With the new formation, the opposition group created one of the largest military groups in Syria fighting the Assad regime, bringing together nearly 30,000 people.

Syria has just begun to emerge from a devastating civil war that began in early 2011 when the Bashar al-Assad regime cracked down on pro-democracy protests with unexpected ferocity. UN officials say hundreds of thousands of people have been killed in the conflict.
