Neither Tehran nor Damascus were pleased with the Arab League's decision to offer opposition leader Sheikh Moaz al-Khatib Syria's seat at this week's summit in Doha.
Two days ago, al-Khatib cited lack of support as his reason for stepping down as leader of the Syrian National Coalition, saying he would continue to work for the revolution from outside the political framework.
Two days later, Qatar Emir Hamad bin Khalifa al-Thani offered him Syria's seat at the summit, noting he supports a political solution to Syria's civil war, which has left more than 70,000 dead.
During his remarks on Tuesday, Al-Khatib made no mention of his resignation, emphasizing his desire for a negotiated end to the fighting and saying the Assad regime has steadfastly refused to meet with the opposition, Asharq al-Awsat reported.
Al-Khatib also called on U.S. Secretary of State John Kerry to support opposition forces to retain control in parts of northern Syria by placing Patriot missiles batteries in Turkey.
Meanwhile, Syrian ambassador to the Arab League Youssef Ahmad blasted the decision to replace a "completely sovereign legitimate state with an illegitimate non-viable monstrosity," Syrian state media reported.
And Iranian state media described the decision as "dangerous behavior."
