Salehi in his message on Friday condemned the Thursday blasts in Damascus and Der'a targeting Syrian citizens and UN peacekeeping forces there.
"Resorting to such violent acts and targeting the innocent people of Syria is indicative of the terrorist groups' approach in opposing the will of the majority of Syrians who with their high turnout in the elections emphasized their support for government's reform pace," he noted.
Salehi also extended sympathy to the Syrian nation and government over the Thursday blasts that killed at least 55 and wounded over 370 people in the country.
The blasts went off near a military intelligence building on Thursday morning. The government and opposition forces blame each other for the attack, which the Security Council condemned as a terrorist attack.
Also on May 9, a bomb attack targeted a Syrian military truck escorting a convoy of UN observers near the southwestern city of Dara'a, wounding six Syrian soldiers.
Syria has been experiencing unrest since March 2011 with organized attacks by well-armed gangs against Syrian police forces and border guards being reported across the country.
Hundreds of people, including members of the security forces, have been killed, when some protest rallies turned into armed clashes.
The government blames outlaws, saboteurs, and armed terrorist groups for the deaths, stressing that the unrest is being orchestrated from abroad.
In October, calm was eventually restored in the Arab state after President Assad started a reform initiative in the country, but Israel, the US and its Arab allies are seeking hard to bring the country into chaos through any possible means. Tel Aviv, Washington and some Arab capitals have been staging various plots in the hope of stirring unrests in Syria once again.
