Syrian regime forces killed 63 people and pounded rebel districts of the flashpoint central city of Homs for a 20th straight day on Thursday.

Seventeen unidentified bodies, 10 children, a media activist and a dissident soldier were among the 63 victims, the Local Coordination Committees, the main activist group spurring protests on the ground, said.

A French reporter who was wounded in the Syrian city of Homs said Thursday she needs urgent medical attention and asked to be evacuated quickly, in a video posted online by anti-regime activists.

Edith Bouvier, a reporter for the French daily Le Figaro, made the appeal in the footage, sitting alongside French photojournalist William Daniels, who said he was not wounded but also keen to be extracted urgently.

An eventual fall of Syria's regime, followed by the rise of an Islamist government could create a quandary for Jordan, a small country that has strategic ties with its northern neighbor, analysts say.

At the same time, even if Syrian President Bashar al-Assad's regime survives pro-democracy protests against his 11-year rule, relations between Amman and Damascus are unlikely to improve, at least in the short term.

Arab and Western powers will challenge the Syrian regime to accept a proposal to allow in humanitarian aid at the "Friends of Syria" meeting in Tunis on Friday, a U.S. official said.

U.S. Secretary of State Hillary Clinton discussed the "unified humanitarian proposal" with counterparts on the sidelines of an international conference on Somalia in London on Thursday, the official said on condition of anonymity.

Syrian President Bashar Assad's regime will not fall and Iran stands beside it, the top foreign policy adviser to supreme leader Ayatollah Ali Khamenei said on Thursday.

"The Islamic Republic of Iran supports the Syrian government and will oppose those who act against Syria," Ali Akbar Velayati said in remarks reported by the Fars news agency.

International investigators have submitted a list of Syrian military and political officials suspected of crimes against humanity to the U.N.'s top human rights official, their report said on Thursday.

"The commission has deposited with the High Commissioner (for Human Rights, Navi Pillay) a comprehensive database containing all evidence collected," said the report from an international commission of inquiry.

International powers called Thursday for urgent action on Somalia, warning at a meeting in London that the world will "pay the price" for failing to tackle political unrest, Islamist militants and pirates.

British Prime Minister David Cameron, U.S. Secretary of State Hillary Clinton and U.N. chief Ban Ki-moon were among officials from about 50 countries and organizations gathered to discuss a roadmap for Somalia's fragile government.

Syria's government has "manifestly failed" to protect its people, an inquiry commissioned by the U.N. Human Rights Council said on Thursday.

"The human rights situation in the Syrian Arab Republic has deteriorated significantly since November 2011, causing further suffering to the Syrian people," wrote the international commission of inquiry after conducting 136 new interviews since its previous report last November.

The Syrian regime was not responsible for the deaths of two Western journalists who "sneaked" into the country, the foreign ministry said on Thursday.

"We reject statements holding Syria responsible for the deaths of journalists who sneaked into its territory at their own risk," said a ministry statement carried by SANA state news agency.

British and French authorities are coordinating with the Lebanese Red Cross to transfer four wounded foreigners from Syria to Lebanon, An Nahar daily reported Thursday.

The newspaper said the injured include three British nationals and a French.
