After 18 months, and over 20,000 dead, there's still no end in sight for Syria. Martin Nesirky, spokesperson for U.N. Secretary General Ban Ki-Moon, explains the U.N.'s strategy going forward.
Syrian rebels are trying to fend off a ground offensive by government troops in Syria's largest city of Aleppo. There are reports the opposition have withdrawn from some densely populated neighborhoods but are holding their ground in others.
Kofi Annan has resigned as the UN Special Envoy to Syria as the battle to take over Syria's largest city, Aleppo, continues. The violence supports Annan's statements of calling Syria "impossible" as the battles only seem to get worse.
With the Syrian Army closing in on the Free Syrian Army in Aleppo, a Syrian-American who's family lives in the city tries to understand what the fighting means for the local population, and what will happen next.
