In a phone call to his Syrian counter part Walid al-Moualem, Iranian foreign Minister Ali Akbar Salehi strongly denounced Damascus Wednesday suicide bombing attack and said foreign backing for terrorist acts would not succeed in destabilizing Syria.

"The Islamic Republic of Iran has repeatedly condemned violence and resorting to destructive measures, and believes that the only way of resolving the current crisis in Syria is through talks" Salehi told al-Moualem.

"Sending weapons and ammunition into the country and support from some regional and international players through terrorist actions that target the robust stability and security of Syrian nation will not lead anywhere," an Iranian foreign ministry statement said about the attack.

"Any type of instability in this country can fuel convulsion and crisis in the region and cause wider violence and unrest," the statement added.
