Syrian rebels attacked a key army base in the northwest province of Idlib on Friday, the last regime bastion in the region, and regime warplanes launched air raids in Damascus province, a watchdog said.

The Syrian Observatory for Human Rights said several rebel groups pounded Wadi Deif amid violent clashes on the ground while regime warplanes launched air strikes around the army base.

Syrian Interior Minister Mohammed al-Shaar, who was wounded in a bombing and was brought to Beirut for treatment a week ago, flew home after Lebanese authorities received information that international arrest warrants could be issued against him, a top security official said.

Al-Shaar left to Damascus on a private jet, officials at Beirut's Rafik Hariri International Airport said Tuesday.

Egyptian President Mohamed Morsi on Wednesday hailed an Islamist-backed charter he pushed through despite fierce opposition protests as "a new dawn" for his country, and said he would now tackle a teetering economy.

In a televised national address, Morsi said he would reshuffle his government and renewed an offer of dialogue with the largely secular opposition.

More than 60 civilians were killed on Sunday in a strike by Syrian regime warplanes on people queuing outside a bakery in the rebel-held town of Halfaya in the central province of Hama, a watchdog said, as regime warplanes pounded the capital's suburbs and the northern province of Aleppo.

The Syrian Observatory for Human Rights, which had earlier reported "dozens" killed, said the death toll could rise as at least 50 people had also been critically wounded.

U.N.-Arab League peace envoy Lakhdar Brahimi arrived in Syria on Sunday for talks on the country's crisis, Agence France Presse reported.

Brahimi entered Syria via a land border crossing with Lebanon after arriving earlier in the day at the Rafik Hariri International Airport from Cairo.

While doomsayers hunkered down to await the coming apocalypse, others took a more lighthearted view Friday of a Mayan prophecy of the world's end and marked the event with stunts and parties.

Interpretations of the Mayan "Long Count" calendar point to an era of more than 5,000 years coming to a halt on December 21, although in Sydney it was business as usual.

Loyalty to the Resistance bloc MP Nawwaf al-Moussawi slammed on Thursday claims by defected Syrian cleric Abdul Jalil Saeed that Syria was planning on assassinating Mufti of Tripoli and the North Sheikh Malek al-Shaar.

He said: “The claims are lies and baseless.”

Free Patriotic Movement leader MP Michel Aoun slammed on Tuesday the March 14 camp's obstruction of parliamentary work, accusing the “minority of practicing a dictatorship” in Lebanon.

He said after the Change and Reform bloc's weekly meeting: “I assure the people that no unrest will take place if the parliamentary elections are not staged due to the March 14 camp's obstruction.”

U.S. journalist Richard Engel, who was freed after being held hostage for five days in Syria, said Tuesday that his captors were taking him to an alleged Hizbullah stronghold when he was set free by rebels.

"This was a group known as the shabiha. This is a government militia. They are loyal to President (Bashar) Assad," Engel said about his captors.

The United States on Monday named former information minister Michel Samaha a "specially designated global terrorist" for allegedly aiding the regime of Syrian President Bashar Assad to launch attacks in Lebanon.

The U.S. Department of the Treasury issued a statement saying that Samaha, pursuant to Executive Order (E.O.) 13441 which targets persons "undermining Lebanese sovereignty, including those who are supporting attempts by the Assad regime to incite violence inside Lebanon", is now a Specially Designated Global Terrorist under E.O. 13224.
