Horror escalates in Syria as U.N. tries again to reach resolution At least six people are killed Saturday in Homs, an opposition activist group says Activist: The regime shells targets multiple times, making rescuing the wounded dangerous Saudi Arabia drafts a U.N. resolution that would condemn Syria's killing and persecution of protesters Russia's U.N. envoy says the international community must address armed rebels (CNN) -- As U.N. diplomats make another attempt to condemn Syria's massacre of civilians, one resident in the besieged city of Homs pleaded for President Bashar al-Assad's regime to have mercy on the most innocent victims. "We just want from Assad to give us permission to move the injured baby -- they are just the babies," said an activist named Omar. They have to leave the area to have a good treatment. ... He don't even let us save and treat our (injured) babies. At least six people were killed Saturday morning in Homs, according to the Local Coordination Committees of Syria, an opposition group that organizes and documents protests. Opposition activists say hundreds of people have died in Homs in the past week as the government tries to eliminate the opposition through indiscriminate shelling and sniper fire. "Today is the seventh day in a row we're under shelling -- nonstop bombardment," Omar said Saturday. He said pro-government forces have surrounded the area with thousands of soldiers and dozens of tanks -- "not the normal tanks. Big tanks. Russian tanks. And attempts to retrieve the dead or rescue the wounded can be equally fatal. "The Assad army is using (a) horrible way to shell the same point twice or more than one time, so it's very dangerous to come close any place has been targeted," Omar said. World leaders have tried to pass resolutions denouncing the slaughter, but have been stymied by Russia and China in sending a unified message. Almost a week after Russia and China vetoed a U.N. Security Council resolution intended to stop the killing, Saudi Arabia has drafted a similarly worded document -- but one that lacks the same punch. The Saudi draft resolution will be submitted to the U.N. General Assembly, where vetoes are not allowed, but resolutions are not legally binding. The three-page draft "strongly condemns" the violations of human rights by Syrian authorities. It cites "the use of force against civilians, arbitrary executions, killing and persecution of protesters, human rights defenders and journalists, arbitrary detention, enforced disappearances, interference with access to medical treatment, torture, sexual violence and ill-treatment, including against children." The text was provided to CNN by a diplomatic source on the condition that it not be posted in full because it could be amended. In addition, the U.N.'s Special Advisers on the Prevention of Genocide and on the Responsibility to Protect reiterated a concern it first expressed last July that "widespread and systematic attacks against civilians could constitute crimes against humanity under international criminal law." Russia, which has major trade ties with Syria, has said it supports an end to the violence, but has said the situation is for Syrians to resolve. The country's U.N. ambassador, Vitaly Churkin, said Russia vetoed the resolution because it disagreed with the text. "We do believe that, in order to stop violence, armed methods must be stopped not only by the government, but also by the opposition," Churkin said. That was the key flaw of the draft resolution. U.N. officials estimate 6,000 people have died since protests seeking al-Assad's ouster began nearly a year ago. The Local Coordination Committees, a network of opposition activists, puts the toll at more than 7,300. Al-Assad's regime has repeatedly said that its crackdown is aimed at armed gangs and foreign terrorists bent on destabilizing the regime. But U.S. Ambassador to Syria Robert Ford said the truth is obvious. "We know who's shelling Homs," he said. It's not the opposition, it's the government. He cited a satellite photo of Homs, posted on the Facebook page of the U.S. embassy in Damascus, showing a city marred by craters and lines of armored vehicles sitting in front of burned-out buildings. The armed opposition has rifles, machine guns, grenades, but it doesn't have artillery. Only one side has artillery," Ford said. One opposition activist, speaking under the pseudonym "Danny," said last week that the army launched a renewed attack on Homs after dozens of soldiers defected and fled into the city. Since then, the violence has continued unabated. But some residents hold their hopes on the defectors from the Syrian regime, some of whom now fight for the opposition Free Syrian Army. On Friday, 10 government troops were killed after defectors set off an improvised explosive device and lobbed hand grenades at military vehicles in Idlib province, according to the Syrian Observatory for Human Rights, an opposition activist group. On the same day, twin blasts tore through government buildings in the Syrian city of Aleppo, which the government promptly blamed on "terrorists." Syrian state-run TV said the "terrorist attacks" left 28 dead and 235 wounded, including an unknown number of soldiers. CNN cannot independently confirm details of the fighting in Syria because the government has severely limited the access of international journalists. Opposition activists in Homs describe bomb explosions from Syrian forces every few minutes, wounded people bleeding to death in the streets because they can't get medical attention, and snipers picking off civilians running for cover. Video allegedly from Homs and posted online shows rubble and the remains of buildings all around as gunfire is heard in the background. Omar said he wants al-Assad out by any means necessary. (We) want not just the international world, the international army -- we want the devil to come and kick Bashar al-Assad out.
