BEIRUT — The resignation of Kofi Annan, the point man for international efforts to bring peace to Syria, emphatically confirmed what events there had already been making clear: The country's fate is far more likely to be decided by force than by negotiations.
The former U.N. secretary-general's announcement Thursday that he was ending his attempt to negotiate an end to the conflict came amid a sharp increase in fighting that began last month after a bomb killed four top security aides to President Bashar Assad.
Government forces subsequently pushed insurgent bands out of Damascus, the capital, but they are now locked in what could be a decisive battle for the northern city of Aleppo, Syria's commercial hub and most populous urban center.
"Most people have concluded that this is not going to be settled by talk at the U.N., but by developments on the ground," said Robert Malley, a former Clinton administration official now with the International Crisis Group think tank.
In comments to reporters Thursday, Annan voiced an opinion he had never before uttered publicly, that, as part of the solution he had been seeking for Syria, Assad would have to go.
"The transition meant President Assad would have to leave sooner or later," Annan said in Geneva.
He cited the Syrian government's "intransigence" and the opposition's "escalating military campaign" as major impediments to his peace efforts, along with a lack of unity in the international community on how to deal with the crisis.
The conflict in Syria, analysts say, has already moved into a new phase that in some ways resembles 1980s Afghanistan, a kind of proxy war for foreign interests in which Western-backed guerrillas are fighting to topple an ally of Moscow.
Although the Kremlin does not have troops in Syria, as it did in Afghanistan, Assad received diplomatic cover from Russia, a longtime ally. And Assad also maintains the backing of Iran, a Shiite Muslim neighbor, and Tehran's Hezbollah, the Lebanon-based Shiite group.
The Obama administration reportedly has signed off on clandestine action by the Central Intelligence Agency on behalf of the Syrian rebels seeking to overthrow Assad. The White House has also agreed to bolster "non lethal" aid to the opposition and make it easier for outside groups to assist the rebels.
The United States and its allies are providing increasing amounts of aid to a highly decentralized rebel force that has a substantial Islamist element, including some admitted Al Qaeda sympathizers.
Washington has said it is not supplying arms to the rebels. That task appears to have been outsourced to allies Saudi Arabia and Qatar. Those Persian Gulf monarchies, dominated by Sunni Muslims, are intent on helping Syria's Sunni majority overthrow Assad's government, which is dominated by the Alawite sect, an offshoot of Shiite Islam.
The departure of Annan, who served since late February as the United Nations and Arab League peace envoy to Syria, would seem to signal the unraveling of his six-point peace plan. In Syria, both sides in the conflict have long ignored Annan's blueprint, which, among other things, called for the withdrawal of troops and armor from populated areas.
Instead, the small contingent of U.N. observers still in Syria said this week that the government had begun using jet fighters, a significant escalation of tactics.
Meanwhile, insurgents were deploying tanks and other heavy weaponry they had seized from the military. They reportedly were firing tank rounds Thursday at a government air base north of Aleppo.
The brutality of the conflict is increasingly evident, with almost daily reports of "massacres" by both sides. A widely circulated video posted on YouTube this week documented the execution of alleged pro-government militiamen by rebels.
Annan, a Nobel Peace Prize laureate, voiced deep frustration with his effort to overcome profound divisions among global powers on how to stop a conflict that the U.N. says has already cost more than 10,000 lives.
"I can't want peace more than the protagonists, more than the Security Council, or the international community for that matter," Annan said. "Syria can still be saved from the worst calamity if the international community can show the courage and leadership necessary."
The spillover effect has already been enormous. Fighting has sent more than 200,000 refugees streaming into neighboring nations, including Lebanon, Jordan, Turkey and Iraq. Cross-border battles have erupted along the Lebanese frontier, and Turkey moved up troops and antiaircraft batteries to its border after Syria shot down a Turkish warplane over the Mediterranean.
Neighboring Israel is concerned that Syria's substantial chemical and biological weapons could fall out of government control.
