DAMUSCUS/PARIS  - Violence raged on Monday across Syria, where at least 36 people, most of them regime forces, were reported killed as clashes erupted in several restive provinces, monitors said.The deadly violence came even as UN-Arab League envoy Kofi Annan arrived in Damascus to try to salvage a battered ceasefire, a day after monitors reported 90 people killed in Syria, more than a third of them in the central city of Hama.The Syrian Observatory for Human Rights said clashes raged in several provinces on Monday, including Idlib in the northwest and Daraa in the south, where the uprising against the regime first erupted more than 14 months ago.Five civilians were among those killed on Monday, including a 14-year-old boy who was shot dead by a sniper in Hama’s Al-Faria neighbourhood, the Britain-based Observatory said.Another two civilians, including an old man, were shot dead inside their home in Nawa, in southern Daraa, by regime forces, the watchdog added.Three rebel fighters and a member of the pro-regime shabiha militia were also killed by gunfire on Monday.France will host a Friends of Syria meeting in Paris, the French president’s office announced Monday a day after Francois Hollande and British Prime Minister David Cameron held talks on the crisis.In a statement condemning the Damascus regime’s use of artillery in a massacre that killed at least 108 people, the president’s office said the country’s leaders would have to answer for their “murderous folly”.Syria’s main opposition coalition called on Monday for countries that support the anti-regime uprising to honour their promises by helping Syrians defend themselves.“The Syrian National Council calls (on) brothers and friends of the Syrian people to help before it’s too late,” the exiled group said in a statement, calling for effective means of “self-defence to stop the demolition of Syrian society.”Stopping short of explicitly calling on countries to arm the opposition, the SNC statement reiterated calls on the international community to take “urgent action in order to stop the killing of civilians.”Rebel fighters should fulfill “their duties in the defence of Syrian civilians and... be prepared to liberate Syria from the hands of Assad’s gangs,” the statement added.Rebels in Syria are partly responsible for the massacre of more than 100 people in the Houla region, Russian Foreign Minister Sergei Lavrov says.Mr Lavrov, whose government a close ally of the Syrian regime, said some victims had been killed at close range in a district controlled by rebels.The UN condemned the killings, saying government artillery was involved.
