CAIRO (AP) -- Leaders at an Islamic summit on Thursday urged a dialogue between the Syrian opposition and regime just as a new initiative for talks proposed by an anti-government leader appeared to be unraveling.
Like previous diplomatic initiatives on Syria, opposition chief Mouaz al-Khatib's call for talks made less than a week ago appeared doomed to failure. And with troops and rebels clashing for a second day around Damascus, frustrated Syrians dismissed the calls for dialogue as empty talk.
"All of this does not concern us," said Iyad, a Syrian fighter on the outskirts of the capital Damascus, which has witnessed heavy fighting in the last two days.
Iranian President Mahmoud Ahmadinejad, whose country is Syria's closest ally in the Middle East, attended the summit and said at a news conference Thursday that he supported dialogue. He added that Egypt, Turkey and Iran were moving toward cooperation on Syria. But he also defended Bashar Assad regime, warning against meddling in the domestic affairs of other countries.
U.N. Secretary-General Ban Ki-moon also strongly welcomed al-Khatib's proposal for political talks and expressed hope that Syrian authorities would accept it.
He strongly criticized Syria's President Bashar Assad for using terrorists as a justification to kill civilians and shell villages.
The U.N. chief told a group of journalists Thursday that the Syrian crisis didn't start because of terrorism -- but he said because Assad continued to kill his own people, terrorist elements are now taking advantage of the turmoil.
"He could have stopped this violence a long time ago and this political dialogue could have commenced a long time ago," Ban said. "But he has been continuously killing, and he has not been listening to his own people. That's why people, out of frustration, out of anger, they have been fighting against their own government."
The Syrian civil war is largely at a stalemate, with neither side making significant battlefield gains likely to bring about a military victory any time soon.
But the international community has been at a loss for ways to end the carnage, with both sides showing no real interest in a political settlement.
At the end of a two-day summit in Cairo, the 57-member Organization of Islamic Cooperation urged Syrian opposition forces and members of the regime whose hands are not tainted by violence to hold talks on resolving the nearly 2-year-old conflict.
In the final statement of the conference, they called for concrete efforts to reach a settlement "that would preserve the rights of the Syrian people and ensure the unity and the safety of their land."
The statement did not specifically refer to the recent dialogue offer by al-Khatib, who has said he would be willing to sit down with regime members on condition they release 160,000 political prisoners.
His offer sparked criticism from fellow opposition activists who say the regime has killed too many people to play a role in the conflict's solution.
On Thursday, al-Khatib appeared to be backing away from the offer. He demanded that the regime release all female political prisoners by Sunday or he would scrap his initiative.
"The regime has until Sunday to begin releasing detainees, especially women. This should be the introduction of prisoners' release," he told BBC Arabic in an interview.
Al-Khatib's offer followed meetings he had held separately with Russian, U.S. and Iranian officials on the sidelines of a security conference in Munich last weekend. Russia and Iran are Syria's two closest allies.
The government has ignored his offer. But one lawmaker said the talks should be without preconditions.
Many of al-Khatib's colleagues in the Syrian National Coalition say President Assad must step down before there can be any negotiations.
Participants at the Cairo summit did not call on Assad to step down, but the meeting exposed conflicting views among Muslim and Arab nations about the Syrian civil war. At past summits, many nations, including Egypt, demanded that Assad go.
Egypt's Islamist President Mohammed Morsi, elected after an uprising ousted his authoritarian predecessor Hosni Mubarak, sharply criticized Assad's embattled regime in his address to the summit. But he did not directly call for him to go as he had in the past.
He said the Syrian government "must read history and grasp its immortal message: It is the people who remain and those who put their personal interests before those of their people will inevitably go."
The summit's final statement also stressed support for a working group proposed by Morsi last year, made up of the leaders of Egypt, Turkey, Iran and Saudi Arabia to address the Syria crisis.
