Western Powers to Press Syria Resolution as U.N. Details 'Chilling' Sarin Attack

Careful not to blame either side for a deadly chemical weapon attack, U.N. inspectors reported Monday that rockets loaded with the nerve agent sarin had been fired from an area where Syria's military has bases, but said the evidence could have been manipulated in the rebel-controlled stricken neighborhoods.

The U.S., Britain and France jumped on evidence in the report — especially the type of rockets, the composition of the sarin agent, and trajectory of the missiles — to declare that President Bashar Assad's government was responsible.

Russia, Syria's closest ally, called the investigators' findings "deeply disturbing," but said it was too early to draw conclusions. The Syrian government's claims that opposition forces were responsible for the attack "cannot be simply shrugged off," Russian Ambassador Vitaly Churkin insisted.

The conclusions represented the first official confirmation by scientific experts that chemical weapons were used in Syria's civil war, but the inspectors' limited mandate barred them from identifying who was responsible for the Aug. 21 attack.

"This is a war crime," U.N. Secretary-General Ban Ki-moon told the Security Council when he presented the report.

Ban said the report prepared by the experts "makes for chilling reading."

"The results are overwhelming and indisputable. The facts speak for themselves."

Ban called it "the most significant confirmed use of chemical weapons against civilians since Saddam Hussein used them" in Halabja, Iraq, in 1988, and "the worst use of weapons of mass destruction in the 21st century."

The deep division between Western backers of rebels seeking to overthrow Assad and Russian and Chinese supporters of the regime has paralyzed the U.N. Security Council since the Syrian conflict began 2 1/2 years ago.

Even though the United States and Russia agreed Saturday on the framework to put Syria's chemical weapons stockpile and precursors under international control for future destruction, their top diplomats were at odds Monday over a new Security Council resolution that would make the deal legally binding — and whether there should be a reference to possible military enforcement if Syria doesn't comply.

After months of negotiations, the U.N. inspectors went to Syria to visit the sites of three alleged chemical attacks earlier this year and were in the capital of Damascus on Aug. 21 when reports and videos began surfacing of a shelling attack in which victims experienced shortness of breath, disorientation, blurred vision, nausea, vomiting, weakness and a loss of consciousness.

They finally gained access to three towns where the Aug. 21 attack occurred, and on one occasion their convoy was hit by sniper fire, but the inspectors were nonetheless able to collect a large amount of material and talk to survivors and witnesses.

"The environmental, chemical and medical samples we have collected provide clear and convincing evidence that surface-to-surface rockets containing the nerve agent sarin were used ... in the Ghouta area of Damascus," their report said.

"The conclusion is that chemical weapons have been used in the ongoing conflict between the parties in the Syrian Arab Republic, also against civilians, including children, on a relatively large scale," they said. "This result leaves us with the deepest concern."

The rebels and their Western and Arab supporters have blamed Assad's regime for the attack in the rebel-controlled area of Ghouta. The Syrian government insists the attack was carried out by rebels. The U.N. report mentions the Ghouta areas of Ein Tarma, Moadamiyeh and Zamalka, all of which were featured in videos of victims that emerged after the attack.

The U.N. report did not mention how many people were killed in the Aug. 21 attack. The U.S. says more than 1,400, but other death toll estimates have been far lower.

The report cited the following evidence to support its conclusions:

— Rockets and fragments were found to contain sarin. "Several surface-to-surface rockets capable of delivering significant chemical payloads were identified and recorded at the investigated sites," the investigators said. They said that "of primary interest was the intact rocket motor found coincident to the impact crater" in Moadamiyah. "This rocket motor was noted to have stone and earth debris impacted in the front section of the motor identical to that found in the crater. There was no indication of damage around the crater area having been caused by blast or explosives. This implies that the warhead was not present upon final impact," they said.

— The approximate capacity of liquid in the warhead is "according to the measurements between 56 +/- 6 liters."

— In Zamalka and Ein Tarma, "the two teams worked in parallel and identified the same type of munition at both sites. The munition had features noted as being consistent with that of an unguided rocket."

— Of the five impact sites investigated by the mission, "three do not present physical characteristics allowing a successful study of the trajectories followed by the rockets involved, due to the configuration of the impact places. However, Impact site number 1 (Moadamiyah) and Impact site number 4 (Ein Tarma) provide sufficient evidence to determine, with a sufficient degree of accuracy, the likely trajectory of the projectiles."

— Close to the impact sites, in the area where people were affected, inspectors collected 30 soil and environmental samples — far more than any previous U.N. investigation — and in a majority of the samples, "the environment was found to be contaminated by sarin," its by-products, and "other relevant chemicals, such as stabilizers."

— Blood, urine and hair samples from 34 patients who had signs of poisoning by a chemical compound provided "definitive evidence of exposure to sarin by almost all of the survivors assessed."

— More than 50 interviews with survivors and health care workers "provided ample corroboration of the medical and scientific results."

"The large-scale use of sarin, the direction of the rocket attacks, and kind of rockets used in the attacks all point to use by Assad's forces beyond reasonable doubt," said Daryl Kimball, executive director of the Washington-based Arms Control Association.

"The conclusions reached by the United States and European governments would now appear to have received corroboration by a source the Russians and Syrians will have trouble discrediting," Kimball said.

The inspectors described the rockets used to disperse the sarin as a variant of an M14 artillery rocket, with either an original or an improvised warhead. The report said the rockets that hit two of the suburbs — Zamalka and Ein Tarma — were fired from the northwest, but it didn't say who launched them.

"Based on the orientation of the impact craters, orientation of certain surviving munition components and other damage in the areas, the rockets are believed to have arrived from the northwest," said the report.

The inspectors did not provide a location for the rockets' launch site, but Qassioun Mountain, where the Syrian military is known to have bases, is roughly northwest of both suburbs.

One of the photographs taken by the inspectors appeared to show possible Cyrillic, or Russian, engravings on one of the rocket casings.

"This was no cottage industry use of chemical weapons," Britain's U.N. Ambassador Mark Lyall Grant said.

"To put it in perspective, just on those rocket samples that they were able to examine, they had a payload of a total of 350 liters, which is 35 times the amount that was used in the Tokyo subway" in 1995, he said, adding that the inspectors also confirmed "that the quality of the sarin was superior" both to that used in Tokyo and also to what was used by Iraq against Iran.

U.S. Ambassador Samantha Power noted that chief inspector Ake Sellstrom said the weapons "were professionally made."

"It defies logic that the opposition would have infiltrated the regime-controlled area to fire on opposition-controlled areas," she said. "Only the regime could have carried out this large-scale attack."

But Churkin wondered why there were no reports of casualties among opposition fighters if government forces fired rockets filled with sarin to try to oust opposition groups from the area.

"Is it theoretically possible to fire five or six rockets and miss your opponent?" he asked.

The inspectors cautioned that the five sites they investigated had been "well- traveled by other individuals prior to the arrival of the mission."

"During the time spent at these locations, individuals arrived carrying other suspected munitions indicating that such potential evidence is being moved and possibly manipulated," the report said. The areas were under rebel control, but the report did not elaborate on who the individuals were.

In the report, Sellstrom said the team was issuing the findings on the Ghouta attacks "without prejudice" to its continuing investigation and final report on the alleged use of chemical weapons in three other areas. Ban said he expects the inspectors to return to Syria "as soon as possible" to complete their investigation.

Under an Aug. 13 agreement between the U.N. and the Syrian government, Sellstrom's team was scheduled to investigate an alleged chemical weapons attack on March 19 on the village of Khan al Assal outside Aleppo and alleged attacks on two other sites that were kept secret for security reasons. The inspectors' report for the first time identified the two sites still to be investigated as Sheik Maqsood and Saraqueb.

U.S. Secretary of State John Kerry and his French and British counterparts worked on a two-pronged approach to Syria: They called for enforceable U.N. benchmarks for eradicating the chemical weapons program and an international conference bolstering the moderate opposition.

An agreement reached with the Russians calls for an inventory of Syria's chemical weapons program within one week, with all components of the program out of the country or destroyed by mid-2014.

The next step must be a decision by the executive committee of the Organization for the Prohibition of Chemical Weapons, which implements the convention that Syria has agreed to join, to endorse the U.S.-Russian agreement. The OPCW is based in The Hague, Netherlands, and it isn't certain when it will meet, although several diplomats said probably later this week.

Once the OPCW approves the agreement, the Security Council must adopt a resolution endorsing both the U.S.-Russian agreement and the OPCW decision.

"This resolution needs to enshrine the OPCW decision in legally binding form, because the OPCW does not have the ability to impose legally binding obligations," Britain's Lyall Grant said.

France and the U.S. insisted that a military response to the Aug. 21 attack remained on the table, and were pressing for a U.N. resolution reflecting that.

"It has to be strong, it has to be forceful, it has to be real, it has to be accountable, it has to be transparent, it has to be timely. All of those things are critical. And it has to be enforced," Kerry said.

"We will not tolerate avoidance or anything less than full compliance by the Assad regime," he added.

Kerry said the agreement "fully commits the United States and Russia to impose measures under Chapter 7 of the U.N. Charter in the event of non-compliance." Chapter 7 resolutions allow for military enforcement.

Lavrov said Chapter 7 was the subject of "fierce debate" during the talks but stressed that "the final document ... doesn't mention it" and that the Security Council resolution being negotiated will not be under Chapter 7.

He said if Syria fails to cooperate, the Security Council can pass an entirely different resolution "which may employ Chapter 7." Lavrov stressed that ongoing attempts to threaten the use of force against Syria would provoke the opposition and disrupt a chance for peace negotiations in Geneva that the U.S. and Russia have been trying to organize.

The Syrian National Coalition — the main umbrella opposition group — welcomed the inspectors' report and urged the Security Council to hold the Assad regime responsible for the Aug. 21 attack and refer the Syrian government to the International Criminal Court for prosecution.

Gen. Salim Idriss, head of the rebel Free Syrian Army, said in an interview on the PBS NewsHour that the inspectors' report makes "very clear that there's a war crime."

He said the Syrian people "are very frustrated because of what's going on and because the international community is not caring anymore about the victims."
