Concern is growing internationally about arming Syrian opposition forces following last week's announcement by the rebel group Jabhat al-Nusra's of its affiliation with al-Qaida.
Speaking in an interview on Syrian state television, Assad alluded to the announcement by Jabhat al-Nusra and compared the link to Western support for the mujahedin in Afghanistan in the 1980s, Britain's Daily Telegraph reported.
