Revered Lebanese spiritual leader Moussa al-Sadr, who went missing in Libya in 1978, died in the prison that he was detained at, al-Liwaa newspaper reported on Tuesday.

The report said that al-Sadr died of natural causes in the summer of 1998, while he was detained at Libya’s capital central prison in an underground cell.

The surviving children of Libya's dead dictator Moammar Gadhafi are determined to destabilize the country, National Transitional Council chief Mustafa Abdel Jalil said on Saturday.

"It is true that Moammar Gadhafi and his children will no longer have a place in the future Libya, but they are still determined to destabilize it and cause many concerns," he said without elaborating.

There is a "gentlemen's agreement" between OPEC members to accommodate increasing output from Libya, the North African country's oil minister said Saturday.

The comments by Abdul-Rahman bin Yazzah indicate that while there is no formal deal among members of the 12-nation Organization of the Petroleum Exporting Countries to cut output, the producer group is willing to take the step as Libya's production ramps up to pre-civil war levels of 1.6 million barrels per day.

The Tunisian-Libyan border post of Ras Jdir reopened in both directions on Thursday after three weeks of being shut over security concerns, an Agence France Presse photographer said.

The U.N. Security Council on Friday lifted sanctions on Libya's central bank and a key investment bank freeing tens of billions of dollars to ease a post-Gadhafi cash crunch.

The United States immediately announced it would unblock more than $30 billion dollars of assets of the Central Bank of Libya and its subsidiary, the Libyan Foreign Bank (LFB). Britain said it would release more than $10 billion.

U.S. Defense Secretary Leon Panetta arrived in Tripoli Saturday on the first visit to Libya by a Pentagon chief to study up close the security needs of the new government.

During the visit, which will last only a few hours, Panetta will meet with Defense Minister Osama Jouili and Prime Minister Abdul Rahim al-Kib, said an AFP correspondent traveling with him.

The United States said Friday it was lifting 'most' U.S. sanctions against Libya and unfreezing $30 billion in assets, but kept holdings of former strongman Moammar Gadhafi’s family blocked.

The move followed similar action by the United Nations Security Council as the world seeks to help the fledgling new government in Libya develop in what Washington has called a "responsible" manner.

Washington said Thursday it was "ludicrous" to accuse it of a role in the killing of Libya's Moammar Gadhafi after Russian Prime Minister Vladimir Putin said U.S. Special Forces were involved.

"The assertion that U.S. special operations forces were involved in the killing of Colonel Gadhafi is ludicrous," U.S. Defense Secretary Leon Panetta's spokesman, Captain John Kirby, told Agence France Presse.

French Foreign Minister Alain Juppe issued a new call for Syrian President Bashar Assad to quit on Thursday, accusing his regime of committing crimes against humanity on a daily basis.

"More than 5,000 killed, three million Syrians are affected by bloody repression, unspeakable abuse and daily crimes against humanity," Juppe told university students during a visit to Libya's capital.

Russian Prime Minister Vladimir Putin on Thursday accused the U.S. special forces of being involved in the killing of deposed Libyan dictator Moammar Gadhafi.

"Who did this?" Putin said in his annual televised phone-in with Russians.
