Liberian incumbent Ellen Johnson Sirleaf's party vowed Sunday that she will contest a run-off presidential vote even if the opposition boycotts the polls, fanning fears of new violence in the war-torn west African country.

"If the opposition wants to boycott the process, that will not stop the process," Unity Party campaign director Musa Bility told AFP after the opposition on Saturday rejected as "flawed" provisional results of the October 11 vote placing Sirleaf in the lead.

Opposition parties in Liberia on Saturday said they were pulling out of the elections, claiming fraud, as vote-counting put incumbent President Ellen Johnson Sirleaf in the lead.

"We are pulling out of the process because it is not democratic and there is a lot of fraud," an opposition source said in the wake of the October 11 elections which also included parliamentary and senatorial polls.

Arab foreign ministers will meet in Cairo on Sunday to discuss Syrian President Bashar Assad's crackdown on protests, the official MENA news agency reported.

The agency cited the Arab League's deputy leader Ahmed Ben Helli as saying the meeting would be held at the request of the Gulf Cooperation Council.

U.N. leader Ban Ki-moon on Friday accused Israel of provoking the international community by approving new settlements in Palestinian territories while efforts were being made to jumpstart peace talks.

Ban added that no new settlement would get international recognition as he highlighted growing frustration.

Demonstrators on Friday called for the United Nations to intervene to put Yemeni President Ali Abdullah Saleh on trial in the wake of a crackdown on anti-regime protests that has cost hundreds of lives.

"We want the world to pass a resolution which defends the blood of the revolutionaries," protesters chanted at a huge gathering near "Change Square" in central Sanaa that has become the epicenter of a campaign to oust Saleh.

Syrian security forces killed 10 people on Friday when they opened fire on protesters in several cities, Rami Abdul Rahman of the Syrian Observatory for Human Rights told AFP by telephone.

"Ten demonstrators were killed today," said Rahman.

A meeting that brought together the two foes, former Premier Omar Karami and al-Mustaqbal bloc leader Fouad Saniora, came out with no result after they expressed conflicting viewpoints on the funding of the Special Tribunal for Lebanon.

Saniora stressed after the meeting in Beirut on Wednesday the importance of funding the STL, stating that it is a “debt on Lebanon.”

Libya's new government vowed on Thursday to investigate "every penny" of suspicious oil contracts signed under the former regime, responsible for what it described as "unbelievable" corruption.

"Any corruption under the previous regime will be investigated... There will be specialized committees that will look into all these contracts and agreements starting with the oil sector," the National Transitional Council's oil and finance minister, Ali Tarhuni, told a news conference in Tripoli.

The seven-month-old revolt in neighboring Syria has given hope to Lebanese families trying to find what happened to thousands of loved ones who disappeared during their country's civil war and are believed dead or held in Syrian jails.

"For the first time in many, many years, it's a win-win situation for us -- for all the families of the victims," said Ghazi Aad, head of SOLIDE, a group that for years has been lobbying for Lebanese political prisoners in Syrian jails.

Special Tribunal for Lebanon Registrar Herman Von Hebel expected from Lebanon to pay its share of the tribunal funding by the end of October, An Nahar newspaper reported on Thursday.

“Lebanon has 30 days to pay its share,” Von Hebel said during a press conference in New York.
