Free Patriotic Movement leader MP Michel Aoun on Monday noted that a "drastic change" has occured in Lebanese politics, after the Hizbullah-led alliance forced the collapse of Saad Hariri's unity government last month.

"An entire approach will be changed ... after the downfall of several political parties as well as spiritual and political leaders ... and media outlets," Aoun said after presiding over a meeting for the Change and Reform parliamentary bloc.

Egyptian President Hosni Mubarak came under fresh pressure Monday to step down immediately as opponents said concessions made in landmark talks were not enough to halt a revolt against his 30-year reign.

As a winter sun began to peep through a chill morning mist, thousands of demonstrators emerged from under blankets and tarpaulins in central Cairo's Tahrir Square, which over two weeks has begun to resemble a tented camp.

Some of the main groups behind Egypt's opposition revolt formed a coalition on Sunday, insisting they will not end their occupation of Tahrir Square until President Hosni Mubarak leaves office.

A statement by the "unified leadership of the youth of the rage revolution" vowed not to end their protest in the central Cairo square until seven demands are met -- chief among them "the resignation of the president."

Opponents of Egyptian President Hosni Mubarak's embattled regime on Sunday dismissed as insufficient an offer to include them in political reform plans and renewed their demand that he step down.

In a landmark concession, Vice President Omar Suleiman agreed to sit down with the groups, which included the banned Muslim Brotherhood, but the talks produced no immediate breakthrough in the two-week-old standoff.

The embattled regime of Egypt's President Hosni Mubarak launched landmark talks Sunday with opposition groups, including the Muslim Brotherhood and street protesters who seized Cairo's central square.

As global pressure mounted for newly appointed Vice President Omar Suleiman to negotiate a peaceful transition to more democratic rule, the government took the historic step of meeting with its most long-standing and powerful foes.

A failed assassination attempt on Egypt's vice president, Omar Suleiman, in recent days left two of his bodyguards dead, sources told Fox News.

Such an attempt on the life of Suleiman would mark an alarming turn in the uprising against the regime of President Hosni Mubarak, who only recently named Suleiman as vice president in an effort to quell the unrest and possibly line up a successor, Fox News said.

Egyptian authorities have arrested al-Jazeera's bureau chief and one of its journalists in Cairo, the Doha-based television channel said on Saturday, amid anti-government protests in the capital.

"Egypt's security services have arrested al-Jazeera bureau chief in Cairo Abdel Fattah Fayed and the journalist Ahmed Yousef," the pan-Arab channel, banned since last Sunday from operating in Egypt, reported on its website.

Unknown attackers blew up an Egyptian terminal supplying gas to Israel near the Gaza Strip on Saturday, an official said, amid raging protests against the regime of President Hosni Mubarak.

The attackers blew up the terminal and the pipeline in the town of Lihfen in the Sheikh Zuwayed area of Sinai, 10 kilometers (six miles) from the Gaza Strip, the official said.

Leading Egyptian opposition figure Mohammed ElBaradei has announced that he would not run for president in the upcoming elections.

"No, I will not join in. The best I can do is act as an agent for change," he told Austrian newspaper Der Standard, when asked whether he would compete in presidential elections.

The U.S. military's top officer on Friday cautioned against moves to cut off aid to Egypt due to the unrest against the government of President Hosni Mubarak.

"I would just caution against doing anything until we really understand what's going on," Admiral Mike Mullen said in an interview on ABC News.
