UPDATE (11:45 a.m. EDT) -- AFP reports that the Free Syrian Army is no longer committed to Kofi Annan's peace plan.
(Reuters) - The United Nations said on Saturday that more than 92 people were killed in what activists said was an artillery barrage by government forces in the worst violence since the start of a U.N. peace plan to slow the flow of blood in Syria's uprising.
The bloodied bodies of children, some with their skulls split open, were shown in footage posted to YouTube purporting to show the victims of the shelling in the central town of Houla on Friday. The sound of wailing filled the room.
The carnage underlined just how far Syria is from any negotiated path out of the 14-month-old revolt against President Bashar al-Assad.
"This morning U.N. military and civilian observers went to Houla and counted more than 32 children under the age of 10 and over 60 adults killed," the head of U.N. team monitoring the ceasefire - which has yet to take hold - said.
"The observers confirmed from examination of ordinances the use of artillery tank shells," Major General Robert Mood said in a statement, without elaborating. "Whoever started, whoever responded and whoever carried out this deplorable act of violence should be held responsible."
Activists said Assad's forces shelled the town of Houla on Friday evening after security forces killed a protester and following skirmishes between troops and fighters from the Sunni Muslim-led insurgency fighting Syria's rulers, who belong to the minority Alawite sect.
A British-based opposition group, the Syrian Observatory for Human Rights, said Houla residents fled, fearing more shelling. It said one person was killed in the northern town of Saraqeb when troops fired on a protest against the killing.
Syrian state television aired some of the footage disseminated by activists after the killing in Houla, calling the bodies victims of a massacre committed by "terrorist" gangs.
It also showed video of bodies with what looked like gunshot wounds to the head, sprawled on bloodstained mattresses.
Activists distributed footage appearing to show protests in Aleppo, the largest city in the north.
A member of the fragmented exile group that says it speaks for Syria's political opposition said Assad's forces had killed "entire families" in Houla in addition to the shelling.
"The Syrian National Council (SNC) urges the U.N. Security Council to call for an emergency meeting ... and to determine the responsibility of the United Nations in the face of such mass killings," SNC spokeswoman Bassma Kodmani said.
Although Annan's six-week old ceasefire plan has failed to stop the violence, the United Nations is nearing full deployment of a 300-strong unarmed observer force meant to monitor a truce.
The plan calls for a truce, withdrawal of troops from cities and dialogue between the government and opposition.
French Foreign Minister Laurent Fabius condemned the violence as a "massacre", and said he wanted to arrange a meeting in Paris of the Friends of Syria, a group that brings together Western and Arab countries keen to remove Assad.
Fabius said that "U.N. observers need to be able to complete their mission and the U.N.-Arab League's joint special envoy's exit plan has to be implemented immediately".
In a statement, Arab League head Nabil Elaraby called the killing in Houla a "horrific crime", urging the U.N. Security Council - where Russia and China have protected Syria - to "stop the escalation of killing and violence by armed gangs and government military forces."
Syria calls the revolt a "terrorist" conspiracy run from abroad, a veiled reference to Sunni Muslim Gulf powers that want to see weapons provided to an insurgency led by Syria's majority Sunnis against Assad, a member of the minority Alawite sect.
U.N. Secretary-General Ban Ki-moon said on Friday that recent bomb attacks may have been the work of "established terrorist groups" and urged states not to supply arms to either the government or rebel forces.
"Those who may contemplate supporting any side with weapons, military training or other military assistance, must reconsider such options to enable a sustained cessation of violence," he told the Security Council in a letter.
The United Nations has accused Assad's forces and insurgents alike of grave human rights abuses, including summary executions and torture.
Ban has also expressed fear that Syria's conflict will destabilize neighboring Lebanon, whose delicate sect-based politics has been shaken by tensions among Lebanese foes and friends of the uprising in Syria.
In the latest episode, gunmen in northern Syria snatched a group of Lebanese Shi'ites this week as they were returning from a religious pilgrimage, sparking the worst unrest in years in the Lebanese capital.
Uncertainty over their fate increased tension in Beirut on Saturday, a day after Lebanon's top officials said the release of the hostages and their return home was imminent.
The prime minister said on Friday afternoon they had been freed, but by Saturday there was still no sign of them. A member of the SNC said they were still in captivity, further angering a crowd that had gathered at Beirut's airport to meet them.

Russia Condemns Massacre
Russia says international envoy Kofi Annan will visit Moscow on Monday to discuss the ongoing crisis in Syria.

"We have no doubt that this wrongdoing serves the interests of those powers that are not seeking peace but persistently seek to sow the seeds of interconfessional and civilian conflict on Syrian soil," Russia's foreign ministry said in a statement, according to Reuters.

How Do Syrian Fighters Get Their Arms?
How do Syria's fighters get their arms? An overview put together by Reuters explains that there are three gateways to the country -- Lebanon, Turkey, and Iraq.
Syrian rebels are smuggling small arms into Syria through a network of land and sea routes involving cargo ships and trucks moving through Turkey, Lebanon and Iraq, maritime intelligence and Free Syrian Army (FSA) officers say.
Western and regional powers deny any suggestion they are involved in gun running. Their interest in the sensitive border region lies rather in screening to ensure powerful weapons such as surface to air missiles do not find their way to Islamist or other militants.

Hama Revolutionary Council: More Than 220 Killed
According to the Hama Revolutionary Council, a Syrian opposition group, more than 220 people have been killed in a new alleged massacre in Taramseh. Earlier reports said more than 100 people were killed. "More than 220 people fell today in Taramseh," the Council said in a statement. "They died from bombardment by tanks and helicopters, artillery shelling and summary executions."
Fadi Sameh, an opposition activist from Taramseh, told Reuters he had left the town before the reported massacre but was in touch with residents. "It appears that Alawite militiamen from surrounding villages descended on Taramseh after its rebel defenders pulled out, and started killing the people. Whole houses have been destroyed and burned from the shelling," Sameh claimed.
