Saleh Undergoes Successful Surgery, Opposition Vows to Keep Him Out

Yemen's opposition vowed on Sunday to prevent the return of wounded President Ali Abdullah Saleh from a Saudi hospital, as tens of thousands of protesters celebrated despite doubts over who holds power in Sanaa.

"We will work with all our strength to prevent his return," parliamentary opposition spokesman Mohammed Qahtan told Agence France Presse. "We see this as the beginning of the end of this tyrannical and corrupt regime."

But a spokesman of the rival ruling General People's Congress (GPC) told Al-Arabiya news channel: "President Saleh will return to Yemen within days."

Saleh underwent two operations on Sunday, a Saudi official in Riyadh told AFP on condition of anonymity.

"President Saleh underwent two operations that were successful. The first was to remove a piece of shrapnel from his chest, and the second was neurosurgery to his neck.

"The next procedure will be for cosmetic surgical purposes. The period of convalescence is two weeks, after which he will return to Sanaa," the official said.

Saleh, wounded by an explosion as he prayed at a mosque inside his presidential compound on Friday, was transferred to Saudi Arabia late on Saturday but has not stood down.

The president, 69, flew to Riyadh on a Saudi medical aircraft and was immediately taken to a military hospital, while a second plane carried members of his family, he said.

Saleh suffered "burns and scratches to the face and chest," a Yemeni official had said, playing down the extent of his injuries, after the GPC said he was "lightly wounded in the back of the head."

His regime has blamed the attack on powerful dissident tribal leader Sheikh Sadiq al-Ahmar, whose fighters have been battling government forces in the Yemeni capital since the power transfer plan crumbled last month.

Sheikh Sadiq's office said on Sunday he has agreed to a conditional truce and to pull his forces from public buildings, following a request from Vice President Abdrabbuh Mansour Hadi.

Hadi asked for "a ceasefire and the evacuation of public buildings by armed elements ... which the sheikh accepted on condition that military units and their armed groups also pull back to restore security," an official in Sheikh Sadiq's office said.

The veteran Saleh's eldest son Ahmed, commander of the elite Republican Guard, has remained in Yemen. The opposition says Ahmed was already preparing to take over from his father before a popular uprising broke out in late January.

Saleh's sons must be "forced to hand power over to Abdrabbuh Mansour Hadi," who under the constitution replaces the absent Saleh, according to Qahtan.

"We are ready to cooperate with Abdrabbuh but the problem is whether his children are ready to hand power over to him," said Qahtan.

A source close to the presidency told AFP that the vice president and Ahmed Saleh held a top-level meeting with several military officials late on Saturday, without disclosing the outcome of their talks.

Hadi also met the U.S. ambassador to Sanaa, Gerald Michael Feierstein, the state news agency Saba reported, to discuss "the importance of cooperation with the (opposition) Common Forum" alliance.

State television, meanwhile, broadcast songs in praise of Saleh.

On the ground, however, tens of thousands took to the streets of the capital Sanaa to celebrate what they said was the end of embattled Saleh's 33-year-long autocratic rule.

"Today, Yemen is newborn," sang people who massed in Sanaa's University Square -- dubbed "Change Square" -- the epicenter of anti-regime protests that have raged since January.

"This is it, the regime has fallen," they chanted, as demonstrators slaughtered sheep for a traditional celebration.

In Yemen's second-largest city Taez, a flashpoint of demonstrations south of Sanaa, hundreds were also took to the streets, shouting: "Freedom freedom, Ali has fled."

Saleh has refused to give up power despite four months of anti-regime protests that have left at least 200 people killed across the country.

His security forces have waged a brutal crackdown, while he has repeatedly refused to sign a plan brokered by the Arab monarchies of the Gulf for a peaceful transfer of power.

Separate clashes between gunmen and security forces in Taez on Sunday left four soldiers and three gunmen dead, witnesses and a medic said.

In Sanaa, meanwhile, three soldiers from dissident General Ali Mohsen al-Ahmar's First Armored Division were killed in an "accidental" bomb blast as they gathered to receive their salaries, a military official said.
