More deadly clashes have been reported in Homs, Syria's third largest city and a center of the anti-government movement calling for the ouster of President Bashar al-Assad. At least 21 people were killed as army forces raided the city. Estimates by the United Nations say over 3,000 Syrians have been killed during the civil unrest since the beginning of the year. Sue Lloyd-Roberts, correspondent for the BBC, went to Homs and saw the brutality first hand. The names of the interviewees in her report have been changed to protect their identities.
