Security forces shot dead 17 people in Syria today and rebels killed seven police in an ambush, activists said, after the UN human rights chief put the death toll from nine months of protest against president Bashar al-Assad at 5,000.
The bloodshed in the northern province of Idlib, which borders Turkey, highlighted the accelerating violence in Syria where an insurgency has begun to overshadow what started as peaceful street protests against Dr Assad's 11-year rule.
The UN's Navi Pillay said the death toll was 1,000 higher than an estimate she released ten days earlier. It includes civilians, army defectors and those executed for refusing to shoot civilians, but not soldiers or security personnel killed by opposition forces, she said.
The Syrian government has said more than 1,100 members of the army, police and security services have been killed.
Syria's actions could constitute crimes against humanity, said Ms Pillay, issuing a fresh call for the council to refer the situation to the International Criminal Court.
"It was the most horrifying briefing that we've had in the [UN] security council over the last two years," British ambassador Mark Lyall Grant said after the session, which was arranged despite opposition from Russia, China and Brazil.
The sharp rise in the death toll is bound to lend weight to those arguing for increased international intervention to stop the bloodshed in Syria which some fear is increasingly drifting towards civil war.
Dr Assad (46) whose minority Alawite family has held power over majority Sunni Muslim Syria for four decades, faces the most serious challenge to his rule from the turmoil which erupted in the southern city of Deraa on March 18th.
A violent security crackdown failed to halt the unrest - inspired by popular uprisings in Tunisia, Egypt, Yemen and Libya - which turned bloodier in the last few months as defecting soldiers join armed civilians in fighting back in some areas.
Mutineers from Syria's regular army have banded together to set up the Free Syrian Army whose gunmen have been active in the city of Homs to try and counter pro-Assad snipers who residents say attempt to intimidate the population into submission.
In the latest violence around dawn today, security forces shot dead 17 people in the northern protest hotbed of Idlib, including nine killed in one incident shortly after dawn, the British-based Syrian Observatory for Human Rights said.
Activists in the province told Reuters that the nine people were killed when inhabitants of the town of Kfar Yahmour came under fire after they burned tyres to block a convoy carrying security forces and pro-Assad militia members.
Two more were shot dead and 19 were wounded when security forces opened fire to try to break up a funeral procession, which now often become impromptu protests.
The Observatory said army deserters attacked a convoy carrying security forces, killing at least seven people. There was no immediate report from state media of the attack, but the Sana news agency said security forces killed several members of an "armed terrorist group" in Idlib.
Sana also said border guards foiled an attempt by "an armed terrorist group" to cross into Syria from Turkey yesterday, the second such reported incident in a week. It said they shot dead two of the 15-strong group.
Syria has barred most independent journalists, making it hard to assess conflicting accounts of events there.
Despite the spiralling violence, Syrian authorities held local elections on Monday as part of what they say is a reform process, but Dr Assad's critics described the voting as irrelevant.
In New York, Western envoys on the security council said Ms Pillay's briefing yesterday was horrifying and termed it scandalous that the council, paralysed by opposition from Russia and China, had taken little action on Syria.
"Independent, credible and corroborated accounts demonstrate that these abuses have taken place as part of a widespread and systematic attack on civilians," Ms Pillay said, according to briefing notes seen by Reuters.
French ambassador Gerard Araud said, "It is scandalous that the council, because of opposition from some members and the indifference of others...has not been able to act to exert pressure on the Syrian authorities."
More than 14,000 people were reportedly in detention, at least 12,400 had sought refuge in neighbouring countries and tens of thousands had been internally displaced, Ms Pillay said, also citing "alarming reports" of moves against the city of Homs.
Russian ambassador Vitaly Churkin said he too was troubled by Ms Pillay's report, but said outside intervention could lead to civil war and a far higher death toll.
He repeated accusations that Western countries had gone into "regime-change mode", adding, "the tragedy is that if things were allowed to degenerate and to go in the direction of further provocation, of fanning further confrontation, then maybe (there would be) hundreds of thousands dead."
Russia joined China to block Western efforts to pass a resolution against Syria in the security council.
Syrian ambassador Bashar Ja'afari said Ms Pillay should never have appeared before the council for a session that was part of a "huge conspiracy concocted against Syria from the beginning".
Dr Assad's government portrayed yesterday's municipal polls as part of a process leading to a parliamentary election next year and constitutional reform. But critics say local elections have little meaning in a country where power is highly centralised.
Syrian prime minister Adel Safar urged voters to "stand together to save our country from the conspiracies against us" and Sana said Syrians had flocked to the polls in 9,849 voting centres.
Dr Assad has said reforms cannot be rushed in Baathist-ruled Syria, which is a close ally of Iran, a key player in nearby Lebanon and supporter of militant anti-Israel groups.
