Iran would consider any attack on Syria an attack on itself, a senior government official was quoted as saying on Saturday, in one of Tehran's most assertive defenses of its ally yet.
Iran is a key supporter of Syrian President Bashar Assad who is fighting a near two-year-long revolt. Tehran has already repeatedly warned the West against intervening in the conflict against Assad.
"Syria has a very basic and key role in the region for promoting firm policies of resistance ... For this reason an attack on Syria would be considered an attack on Iran and Iran's allies," said Ali Akbar Velayati, an aide to Supreme Leader Ayatollah Ali Khamenei, according to the Mehr news agency.
"If Assad falls, Iran and Iraq are next in line," he added.
Velayati made similar comments last week,
warning against attempts to topple the Syrian president and saying that Assad's fate was a "red line" for Iran.
Iran has steadfastly backed Assad's rule since an uprising against his
rule began almost two years ago and regards him as an important part of
the axis of opposition against arch-foe Israel.
In September, an Iranian military official was quoted as saying Iran would take action if the United States was to attack Syria.
Shi'ite Muslim power Iran and Syria, whose leader follows an offshoot of Shi'ite Islam, signed a mutual defence pact in 2006, but little is known of its details or whether there are any other signatories.
Iran accuses Western powers and regional states of supporting and arming the Syrian rebels, while the rebels accuse Iran of sending fighters from its Islamic Revolutionary Guard Corps to help Assad crush the uprising.
Khamenei's aide also repeated previous statements made by countless of Iranian officials, insisting Tehran would not give up its nuclear program.
called on the US to reconsider its policies against Iran, using language
taken from the US Declaration of Independence and deeming the "peaceful
uses" of Tehran's nuclear energy as "unalienable rights."
