Syrian Rebels Set Eyes on Divided Aleppo

Syrian insurgents say they have begun a campaign to take control of the divided city of Aleppo. The metropolis was Syria's most populous city before it become a main battleground in the four-year-old civil war. No side has been able to control Syria's main commercial hub, about 30 miles from Turkey, since battle erupted there in 2012. Since fighting started, its UNESCO-listed historic center is now a ruin. The prospect of a rebel offensive in the city is a stark sign of the turn of momentum against President Bashar al-Assad's government, which has lost swathes of territory to fighters in recent months in the northwest, east and south of the country.
