But sources in Syria told FNA on Friday that the country's army had pushed back the terrorists from the vicinity of the Al-Thalaa airbase.
The Syrian Observatory for Human Rights, a UK-based monitoring group, reported that the fighters withdrew under heavy government fire.
"Opposition fighters withdrew from areas … after heavy aerial bombardment and the arrival of reinforcements from the National Defense Forces and Popular Committees," said Observatory chief Rami Abdel Rahman.
Over 210,000 people have reportedly been killed in Syria since the outbreak of the crisis in March 2011.
New figures show that over 76,000 people, including thousands of children, lost their lives in Syria last year alone.
