(CNN) -- Fierce fighting between rebels and Syrian troops raged on the embattled capital's doorstep Saturday, opposition forces told CNN. Free Syrian Army rebels traded gunfire for mortar rounds from President Bashar al-Assad's troops along a critical fault line separating the suburb of Jobar from Damascus itself, said Baraa, a spokesman for the local Revolutionary Military Council, who gave only his first name for safety reasons. "There are heavy ongoing clashes at Eight Azar. If we capture the area it means we have reached the heart of the capital. It means we can cross into Damascus," Baraa told CNN. Rebels appear to be inching closer to a decisive battle for the capital, al-Assad's stronghold, but after nearly two years of fighting the opposition remains wary.
