(CBS News) ANTAKYA, Turkey - Bashar Assad's regime continues battling armed rebels for control of Aleppo, Syria's biggest city. The picture of what's happening is confused, but government forces seemed to be gaining the upper hand Friday morning.
Aleppo's Salaheddin district had been an opposition stronghold, but the government says its driven rebels out of their positions and taken full control of the area.
The rebels call it a tactical retreat, but as they stop to bury their dead on the way out, there are reports that they're running out of ammunition.
Aleppo used to be Syria's bustling commercial hub. Now, it's a warzone.
The Syrians who manage to flee across the border into Turkey - safe from Assad's onslaught, but still fearful for their relatives back home - talk to CBS News with their faces covered.
"The regime is fighting like a coward," one man charges. "They attack us with tanks and war planes, but they don't dare to fight on the ground."
U.N. Secretary-General Ban Ki-moon believes Syria now faces the prospect of a long-term civil conflict, and he says it is a war in which there will be no winners.
