Jon Lee Anderson, staff writer for The New Yorker, just returned from reporting from the front lines in Syria. He tells us who the rebels are in Syria, and how difficult it is to report as a foreign journalist in the country. On Tuesday, reporter Marie Colvin and photographer Remi Ohlik were killed during one of the Syrian military's ongoing assaults on Homs. On Thursday alone, activists estimated that 101 people were killed. Meanwhile, the group "Friends of Syria" will meet in Tunis on Friday to discuss the possibility of dialogue with the Assad regime, but the conflict shows no signs of abating.
