Syria's foreign minister says his country's belief in military victory is greater now because the army "is making great strides in its war against terrorism" with support from Russia, Iran and Lebanon's Hezbollah fighters.

Walid al-Moallem told the U.N. General Assembly's annual ministerial meeting on Saturday that Syria is more determined than ever to eliminate "terrorism" from the country.

He said the President Bashar Assad's government remains committed to political negotiations under U.N. auspices but stressed that any solution must follow two parallel tracks: intensified counter-terrorism efforts and an intra-Syrian dialogue that allows Syrians to determine their future.

He called the "moderate armed opposition" supported by Western and Arab nations "terrorists" who have committed crimes against Syrians "that are no less barbaric" than those of the extremist Islamic State group and al-Qaida.
