Iran's security chief has told President Bashar al-Assad that Syria is part of a vital regional alliance that Tehran will not allow to be broken. During talks in Damascus, Saeed Jalili said Syria was an essential part of an "axis of resistance". The statement came a day after Syrian Prime Minister Riad Hijab defected to the opposition.
According to BBC, Syrian TV showed President Assad greeting Mr Jalili, his first TV appearance in two weeks. President Assad was last seen on state TV on 22 July - four days after a bomb killed four security chiefs in Damascus.
State television said Mr Assad had told Mr Jalili of "the determination of the people and government of Syria to cleanse the country from the terrorists and fight against terrorism unreservedly".
He said Syria would "continue on the path of national dialogue" and that it was "capable of thwarting the foreign conspiracies".
Mr Jalili was quoted as saying: "Iran will not allow the axis of resistance, of which it considers Syria to be an essential part, to be broken in any way."
Correspondents say "axis of resistance" refers to Iran, Syria, Hezbollah in Lebanon and the Palestinian Islamist group Hamas in Gaza. Tehran says it is planning an international meeting on Syria on Thursday.
It is also trying to secure the release of a group of Iranians abducted by rebels from a bus in Damascus on Saturday. As well as Mr Jalili's visit to Damascus, Iranian Foreign Minister Ali Akbar Salehi is holding talks in the Turkish capital, Ankara.
