"The Islamic Republic of Iran is serious about defending Syria's national sovereignty as (part of) an axis of resistance against the Zionist regime and will stay on the side of that nation," Boroujerdi said in a meeting with head of the Syrian parliament's Foreign Affairs Commission Fadiya Daib and head of the National Security Commission Mohammad Sobhi Abu al-Shamat here in Tehran.
"The parliament backs any move in support of Syria against its enemies' conspiracies," Boroujerdi underscored, adding that any solution to the crisis without the Syrian government's agreement is doomed to failure.
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 2011, 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 increasing unrests in Syria.
