Syrian activists say the battle between Opposing fighters and Al-Assad regime's troops for the country's second-largest airport is intensifying. The director of the Britain-based Observatory for Human Rights, Rami Abdul-Rahman, says the fighting Saturday near Aleppo International airport is concentrated around a section of a highway connecting the city with a strategic facility the have been trying to capture for weeks. The Opposing fighters have recently taken control of two military bases protecting the airport. They have also cut off a highway the regime's army has been using to transport troops and supplies there, according to a report of the Associated Press.
