Isis, the Islamic State in Iraq and Syria, which is tied to al-Qaeda, took control of the town in northern Syria on Wednesday from the Free Syrian Army, a larger group backed by the West.
Fighting between the two rebel groups has increased the fears that there would be a war within the civil war.
The clashes have come prior to the Saturday deadline for Syria to hand over its list of chemical weapon inventory and facilities, as part of the deal brokered by Russia and the U.S. for Syria to destroy its arsenal of deadly weapons.
Talks are being held now in Damascus with Sergei Ryabkov the Deputy Foreign Minister in Russia. However, the agreement has hurdles to face going forward, including the differing of opinions between Russia and the U.S.
John Kerry the U.S. Secretary of State said the report from the weapons inspectors from the United Nations definitely proved that the government of Syria was behind the August 21 deadly attack with chemical weapons in Ghouta a suburb of Damascus.
However, Damascus, supported by Russia, has insisted that rebels carried out that attack.
The West is also requesting that any resolution in the U.N. on the chemical weapons in Syria include the threat of the use of military force if there is non-compliance, but the Russians have objected to this being included in a resolution.
President Bashar al-Assad of Syria, said in an interview that it might take as long as a year to destroy the entire stockpile of chemical weapons in Syria and could reach a cost of more than $1 billion.
With the ceasefire in Azaz, an all out war between al-Qaeda linked jihad’s with Free Syrian Army rebels has been averted, if just temporarily.
