At a disadvantage in the skies, Syrian rebels have begun to mount assaults on air bases to stop attacks from planes and helicopters. On Saturday opposition forces reported that they had seized an air base near the Syrian border with Iraq. The rebels are also reportedly seeking antiaircraft missiles. President Bashar al-Assad’s forces have used their air superiority to considerable effect as they battle the lesser-equipped rebels. Now, the attacks mounted by opposition forces seem to be targeting bases from which planes take off to attack rebel territory. Meanwhile, Syrian TV says an explosion has hit an Army post in central Damascus.
