Both official media and an opposition group on Sunday branded as a failure a world powers deal on a transition plan for Syria a day after more than 80 people were reported killed in violence nationwide.

World powers meeting in Geneva on Saturday agreed a transition plan that could include current regime members, but the West did not see any role for President Bashar Assad in a new unity government.

Free Patriotic Movement leader MP Michel Aoun reiterated that the adoption of proportional representation in the parliamentary electoral law will help reflect Progressive Socialist Party leader MP Walid Jumblat’s real political weight, reported An Nahar daily on Sunday.

He told the daily: “Jumblat is suffering from an inferiority complex. He fears the Christians, Shiites, and Sunnis because they outnumber him.”

Russia will offer to host the next round of international talks on the Syria crisis if some progress is made in Geneva on Saturday, Russian news agencies reported.

"Russia will propose holding such a meeting in Moscow," the Russian source close to the ongoing negotiations in Geneva was quoted as saying by Interfax.

Mohammed Morsi took the oath of office on Saturday to become Egypt's first Islamist president and its first elected head of state since Hosni Mubarak's overthrow last year.

The ceremony took place in the constitutional court rather than parliament, the result of an ongoing tussle with the military that took charge after Mubarak's overthrow and insists on retaining broad powers now.

World powers agreed Saturday to a plan for a transition in Syria that could include current regime members, but envoy Kofi Annan doubted if Syrians would pick leaders "with blood on their hands".

U.S. Secretary of State Hillary Clinton made it clear that Washington did not see any role for President Bashar Assad in the new regime, even though there was no explicit call for him to cede power.

At least 53 people were killed, mostly civilians, in violence across Syria on Saturday, and hundreds more were trapped in Douma as regime forces stormed the town in Damascus province, monitors said.

The Syrian Observatory for Human Rights urged the International Committee of the Red Cross and the Syrian Arab Red Crescent to "urgently send medical teams" to Douma.

The advisor of Turkish Foreign Minister Ahmet Davutoglu reiterated that 11 Lebanese pilgrims kidnapped in Syria last month haven’t crossed the border to Turkey.

In remarks to An Nahar newspaper published Saturday, the advisor said: “Turkey has nothing to do with the issue and the kidnapping didn’t take place on our territories.”

Russia said it was looking with optimism at Saturday's Syria crisis talks in Geneva after being told by U.S. Secretary of State Hillary Clinton that the Syrians themselves should decide the makeup of their new government.

"I can confidently say that we have a very good chance tomorrow in Geneva to find a common denominator and mark a path forward," Foreign Minister Sergei Lavrov said after the talks, adding that Clinton had agreed the Syrian governing lineup "can only be decided by the Syrians themselves."

U.N.-Arab League envoy Kofi Annan said "external powers" have encouraged violence in Syria as he issued a new plea for unity ahead of a key international meeting on the conflict on Saturday.

"Many external powers are deeply involved. Despite formal unity behind the six-point plan, mutual mistrust has made them work at cross-purposes," Annan said in a commentary for the Washington Post published Friday.

Russia on Friday called the upcoming Geneva talks on Syria a "positive step" despite fears that the meeting might not go ahead because of disagreements and Moscow's anger at the absence of Iran.

"On the whole, we view the upcoming meeting in Geneva as a positive step in a search for a way to broaden and strengthen the basis of an international consensus," the Russian foreign ministry said in reference to Saturday's meeting.
