Nearly a week after Russia and China vetoed a U.N. Security Council resolution intended to halt the killing in Syria, 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 text was provided to CNN by a diplomatic source on the condition that it not be posted in full because it could be amended.

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."

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."

But it was not clear what impact the words and documents might have. The world body has already shown itself incapable or unwilling to move forcefully to stop the slaughter. The U.N. Security Council last week failed to pass a resolution on Syria after Russia and China vetoed the measure.

The rebuff to the will of much of the rest of the international community was denounced during opposition protests Friday; one protester burned a Chinese flag.

The latest diplomatic effort came hours after twin blasts tore through government buildings in Syria's second-largest city and on a day when thousands of government opponents marched in more than 600 demonstrations nationwide and Syrian artillery shells continued to rain terror on the city of Homs.

The government blamed "terrorists" for the morning explosions in Aleppo, considered one of President Bashar al-Assad's power centers. State media showed burned bodies, police vehicles and buses covered by a dusting of rubble, their seats occupied by shards of twisted metal and more rubble. Lingering shots focused on spots of brown, dry earth tinged by a splattering of red, a grim Jackson Pollock. The state media blamed the blasts on two suicide car bombings that killed 28 people and wounded 235.

Activists put Friday's nationwide death toll at 110. They included 64 civilians, at least six rebels and about 40 from the security forces, according to the Local Coordination Committees, which organizes and documents anti-government protests.

The state-run Syrian Arab News Agency, citing the Ministry of Foreign and Expatriates, blamed "parties that were supported by Arab and Western countries in violation of their Arab and international obligations and in sincere devotion to undermine the safety and security of Syria and its citizens."

The Free Syrian Army, comprising defectors, blamed the government.

Friday's bloodshed brought familiar protestations. "The secretary-general firmly condemns the bomb attacks this morning in the city of Aleppo," said one such e-mail from the spokesperson for Ban Ki-moon. "The secretary-general reiterates his strong conviction that the crisis in Syria can only be solved through a comprehensive peaceful political solution that addresses the democratic aspirations of the Syrian people and ensures the full respect of their human rights and fundamental freedoms."

A satellite photo of Homs, shot last Monday and posted on the U.S. Embassy's website, limns a city landscape pockmarked by craters and burned-out buildings in front of which sit neat lines of armored vehicles.

Al-Assad's regime has repeatedly said that its months-long crackdown is aimed at armed gangs and foreign terrorists bent on destabilizing the regime.

Such remarks were dismissed as "disingenuous" by U.S. Ambassador to Syria Robert Ford. "We know who's shelling Homs," he told CNN in an interview in Paris.

"It's not the opposition, it's the government. That's why I wanted that picture put up on our Facebook account. So people could see there's the artillery and that's what's firing. The armed opposition has rifles, machine guns, grenades, but it doesn't have artillery. Only one side has artillery."

The impact of that artillery and how to muzzle it is likely to be a topic Monday when U.N. High Commissioner for Human Rights Navi Pillay is to address the U.N. General Assembly on Syria.

Sixteen people died in Homs, where shelling and rockets bombarded residents for a sixth consecutive day, according to opposition activists and city residents.

"Random shelling mainly with Katyusha rockets started as usual at 5 a.m. ET today on civilian areas in (the Homs neighborhood of) Baba Amr," according to an amateur videographer identified only by his first name, Rami, because he fears retribution.
