Syrian security forces fired tear gas and live ammunition to disperse thousands rallying Friday in Aleppo in what activists said was the largest protest yet in a city that has largely remained loyal to President Bashar Assad during the country's 15-month uprising.
DAMASCUS: A roadside bomb has exploded in a restive suburb of the Syrian capital as the chief of the U.N. observers was visiting.
No casualties were reported from Sunday's blast in Douma, which damaged a parked Toyota pickup car. It was not immediately clear what the bomb's target was.
Maj. Gen. Robert Mood and a team of observers and journalists were some 150 meters (500 feet) away when the blast went off, blowing off the front of the vehicle.
A U.N. observer team with more than 200 members now on the ground has done little to quell the bloodshed in Syria, and some monitors have even been caught up in the violence themselves.

BEIRUT (AP) — A restive district of the Syrian capital that has been a hotbed of dissent against President Bashar Assad was rocked by fighting overnight between government forces and army defectors, opposition groups said Sunday.
Also Sunday, an anti-Syrian cleric and his bodyguard were shot dead in neighboring Lebanon, where a spillover of Syria's conflict has inflamed tensions and triggered deadly sectarian fighting in recent days.
The Local Coordination Committees and the Syrian Observatory for Human Rights said the Damascus clashes took place in Kfar Souseh early Sunday morning but there were no immediate reports of casualties. The district is a high security area, housing the Foreign Ministry and several security and intelligence agencies. It has also been the scene of frequent anti-Assad demonstrations since the uprising began.
"Violent clashes broke out between rebel fighters and regime troops at a checkpoint in Kfar Souseh district," the Observatory said in a statement. Both the Observatory and LCC said explosions and gunfire were also heard in several other neighborhoods of Damascus.
Syrian rebels claimed in an Internet statement that they carried out a sophisticated attack that killed top political and security officials meeting in the capital. The posting claimed those killed included Maj. Gen. Assef Shawkat, the deputy chief of staff for security affairs; Defense Minister Dawoud Rajha; Interior Minister Mohammad al-Shaar and former defense minister, Hassan Turkmani.
Al-Shaar denied the rebel claims at a press conference. Turkmani was interviewed by state-run Syrian TV in his office, saying the claims were "blatant lies."
Syrian officials rarely respond to claims and statements issued by the opposition and their quick denials on Sunday were unusual.
The revolt against Assad's regime started in March 2011 with mostly peaceful protests calling for political change. The deadly government crackdown led many opposition supporters to take up arms. Now, the regime is facing an armed insurgency targeting government installations, soldiers and security forces.
In March, the U.N. said that 9,000 people had been killed. Hundreds more have died since.
Clashes in the heart of the Syrian capital have become more common recently but are still rare compared to other opposition strongholds in Syria that witness deadly violence almost daily.
A cease-fire that was supposed to start last month has never really taken hold, undermining the rest of international envoy Kofi Annan's plan, which is supposed to lead to talks to end the 15-month crisis.
World powers remain divided on how to end Syria's crisis. The U.S. and other Western and Arab nations have called for Assad to leave power, and the U.S. and European Union have placed increasingly stiff sanctions on Damascus. But with Russia and China blocking significant new U.N. punishments, U.S. officials are trying to get consensus among other allies about ways to promote Assad's ouster.
Visiting Annan deputy Jean-Marie Guehenno held talks Sunday with a three-man delegation from an opposition group inside Syria.
Abdul-Aziz al-Kheir, a spokesman for the National Coordination Body for Democratic Change in Syria, said the talks centered on implementing Annan's plan. He said his group demanded "a genuine and overall cease-fire" as the only path to a political process that could solve the crisis.
President Barack Obama said Saturday that the members of the Group of Eight industrial nations support the U.N.'s peace plan for Syria, but added that it has not taken hold fast enough.
In Lebanon, the anti-Syrian cleric and his bodyguard were on their way to a rally in a remote northern Sunni region when they were shot dead Sunday.
The circumstances surrounding their deaths remain unclear but the state-run National News Agency said Sheik Ahmed Abdul-Wahid and his guard appeared to have been killed by soldiers after their convoy failed to stop at an army checkpoint.
The deaths could add to the tensions between pro and anti-Syrian groups in the region, and there were fears of clashes breaking out as the cleric's supporters blocked roads with burning tires in protest.
The Lebanese army issued a statement, saying it deeply regretted the incident and that a committee will investigate.
Clashes between pro- and anti-Syrian groups in the northern Lebanese city of Tripoli left eight people and dozens wounded this week.
