Fighting, Car Bomb Mar Syria Holiday Truce A powerful car bomb exploded in Damascus and scattered fighting broke out in several areas across Syria Friday, quickly dashing any hopes that a shaky holiday cease-fire would hold for four days. But taking advantage of a lull in fighting in the hours after the truce which went into effect Friday morning, thousands of people took to the streets in several towns and cities, calling for President Bashar Assad's ouster in the largest anti-regime protests in months. The Syrian military has agreed to cease military operations for four days beginning Friday morning to observe the Eid al-Adha holiday, in line with a proposal by international envoy Lakhdar Brahimi that was endorsed by the U.N. Security Council. But there were no arrangements for monitoring compliance, and past cease-fire efforts have collapsed as both sides refused to lay down their arms. In Damascus, a car bomb exploded in a residential area, killing at least five people and wounding more than 30 others, according to state TV and activists. The target of the explosion was not immediately clear. A Damascus resident, who spoke on condition of anonymity fearing reprisals, said it may have been a residential complex for police forces located in the southern Daff el-Shouq district.

Fighting raged near a military base in Syria's north as a cease-fire in the bloody civil war was supposed to go into effect Friday at dawn, activists said, illustrating the difficulty of enforcing even a limited truce coinciding with a Muslim holiday. The Islamic extremist group Jabhat al-Nusra, which is fighting alongside the rebels and has rejected the cease-fire, has claimed responsibility for several past bombings targeting the regime. The group also clashed with government troops at a military base outside the strategic town of Maaret al-Numan, which is on the road between Damascus and the northern city of Aleppo, according to the Britain-based Syrian Observatory for Human Rights, which relies on a network of activists on the ground. Fierce fighting has been going on there for several days. Opposition fighters seized Maaret al-Numan earlier this month, disrupting the ability of the Syrian army to send supplies and reinforcements to the northwest, where troops are bogged down in a stalemate with the rebels in Aleppo, Syria's largest city. And at least 10 people were killed in government shelling and sniper fire in the Damascus suburbs of Harasta and Douma, and in the northern Idlib province, activists said. The violence underscored the complexity of the situation, with the badly fragmented opposition sending mixed signals about the truce, some endorsing it and others rejecting it as irrelevant. Assad's government accepted the truce but left significant loopholes, declaring it would respond to any rebel attack or attempts by foreign forces to intervene. The Syrian military issued a statement later Friday, saying the armed forces had abided by the cease-fire but responded to violations by "armed terrorist gangs" who opened fire on security forces in several locations across the country. The Syrian government routinely refers to rebels seeking to oust Assad as terrorists. Still, an overall decline in violence allowed protesters in Damascus and several other cities to pour into the streets in numbers not seen in months. Protesters rallied after holiday prayers in the capital Damascus and its suburbs, in the northern and southern provinces of Aleppo and Daraa, the central province of Homs and the city of Hama. Three people were wounded when troops tried to disperse protesters in Daraa, the Syrian Observatory for Human Rights reported.
