Iranian President Mahmoud Ahmadinejad condemned the "killings and massacre" in key ally Syria, which has carried out a bloody crackdown on seven months of protests, in an interview with CNN. "We condemn killings and massacre in Syria, whether it is security forces being killed or people and the opposition," Ahmadinejad said, according to excerpts of the interview reported in Farsi by the website of Iran's state broadcaster on Saturday. "We have a clear formula for Syria and that it is for all sides to sit together and reach an understanding... therefore these killings cannot solve any problems and in the long term it will lead to a deadlock," he added.
