Syrian rebels struggle to penetrate cities

The Free Syrian Army, the main rebel group in the country, has managaed to take control of many rural areas outside Damascus, the capital, and Aleppo, the country's commercial hub and largest city.

But the fighters have struggled to gain a foothold in the urban centres of the country's two main cities.

Zeina Khodr reports from the Lebanon-Syria border, where refugees of the conflict are split over the uprising.
