With their country finally liberated from the Gaddafi regime, thousands of Libyans who fled decades ago in fear of their lives are at last free to come home. We accompany the prominent opposition figure Mansour El Kikhia on his emotional journey from the United States, where he campaigned against Gaddafi for 33 years, to his home city of Benghazi, where the revolution that eventually overthrew the regime began, and on to Tripoli, where a transitional government is taking its first tentative steps in remaking the country.
