DAMASCUS, Syria — Syrian government forces for the first time hit the country’s largest Palestinian refugee neighborhood with airstrikes on Sunday, killing at least eight people in the Yarmouk district of Damascus and reportedly driving dozens of formerly pro-government Palestinian fighters to defect to the rebels.
New signs emerged on Sunday of political pressure on President Bashar al-Assad. Mr. Assad’s vice president was quoted as saying neither side could win the war and calling for “new partners” in a unity government, a possible sign that at least some in the government were exploring new ways out of the crisis. The comments came as two close allies, the government of Iran and the leader of the Lebanese Shiite group Hezbollah, appeared to slightly temper their support.
In Yarmouk, flesh stuck to the walls and burned body parts littered the ground at the Sheik Abdul Qader mosque, which had offered shelter to Palestinians and others displaced by fighting in other areas. Minutes before, a reporter saw a Syrian fighter jet fire rockets at the camp. Women, crying children and white-bearded men thronged the streets with hurriedly packed bags, not sure where to look for safety.
For many Yarmouk residents — refugees from conflict with Israel and their descendants — the attacks shattered what was left of the Syrian government’s claim to be a champion and protector of Palestinians, a position that the Assad family relied upon as a source of domestic and international legitimacy during more than 40 years of iron-fisted rule.
“For decades the Assad regime was talking about the Palestinians’ rights,” said a Palestinian refugee who gave his name as Abu Ammar as he debated whether to flee with his wife and five children from the camp, on the southern edge of Damascus. “But Bashar al-Assad has killed more of us today than Israel did in its latest war on Gaza.”
He added: “What does Bashar expect from us after today? All of us will be Free Syrian Army fighters.”
The Palestinian militant group and political party Hamas has broken with Mr. Assad over his crackdown on what began as a peaceful protest movement, and while most Palestinian parties still profess neutrality, a growing number of Palestinians support — and have even joined — the rebels.
The Syrian government long held the loyalty of hundreds of thousands of Palestinian refugees, giving them health care, education, and access to professional careers, among other rights denied by other Arab host countries. But those policies also gave Palestinians a stake and sense of belonging in Syria that has led many to join the uprising.
Several of Mr. Assad’s allies signaled a new push for a peaceful solution. Iran’s Foreign Ministry called for an end to military action, the release of political prisoners and a broad-based dialogue to form a transitional government that would hold free elections, Iran’s state news agency reported.
Mr. Assad’s vice president, Farouk al-Shara, said that neither the government nor the rebels could end the conflict militarily, the pro-Syrian Lebanese newspaper Al Akhbar reported. And he called for a solution involving a cease-fire and brokered by international leaders that would establish a “national unity government with wide powers.”
He added that the battle was for the country’s very existence, not “the survival of an individual or a regime,” and that Syria’s leaders “cannot achieve change without new partners.”
The impact of the statements was unclear. Mr. Shara, a Sunni Muslim like most of the rebels, has been floated by the Arab League as a possible successor, but many of Mr. Assad’s opponents reject any dealings with leaders of the current government.
In neighboring Lebanon, Hassan Nasrallah, the leader of Hezbollah, appeared to acknowledge for the first time that the Syrian uprising is at least in part driven by popular sentiment.
“Today, in Syria,” he said in a videotaped address at a graduation ceremony, “there is a big part of the population with the Syrian regime and a part against it, and the latter armed themselves to fight the regime.”
