The moments when the father, who had spent 30 years in prison, visited his sons' graves were heart-wrenching.

The opposition groups in Syria seized the capital, Damascus, within 12 days through a lightning operation, overthrowing President Bashar al-Assad. Assad, who fled the country with his family, sought refuge in Russia. The combination of a civil war that has lasted for 13 years and external factors prepared the surprising end of the ousted leader.
