UNITED NATIONS — Secretary-General Ban Ki-moon said Friday he believes there will be "an overwhelming report" from U.N. inspectors that chemical weapons were used in an attack in Syria on Aug. 21, but he did not say who was responsible.
The Syrian government and rebels blame each other for the attack in the Damascus suburb of Ghouta. The Obama administration, which says 1,429 people were killed, has said it has evidence that clearly indicates the Syrian government was behind the attack. But Russia, a key ally of Syria, has said it is not convinced by the U.S. evidence.
The U.N. inspectors have a mandate to determine whether chemical weapons were used — and if so, which agent — not to establish who was responsible. But two U.N. diplomats said the report could point to the perpetrators, saying that the inspectors collected many samples from the attack and also interviewed doctors and witnesses.
Ban spoke shortly before the chief chemical weapons inspector, Ake Sellstrom, told The Associated Press that he has completed his report and will deliver it to the secretary-general in New York this weekend.
Ban also said President Bashar Assad's regime "has committed many crimes against humanity."
"Therefore, I'm sure that there will be surely the process of accountability when everything is over," he said.
Asked whether Ban's conclusion was in response to the report, U.N. associate spokesman Farhan Haq said that as far as he knows the report hadn't been completed "so it's not possible for any of us to have seen the report at this present moment."
But he added that Ban "has been in touch with different people including the experts."
The secretary-general spoke at the Women's International Forum. He thought his speech and response to questions were not being broadcast, but they were shown on U.N. television.
Speaking by telephone from the Netherlands, Sellstrom said he didn't know exactly when the report would be released publicly. He confirmed that "it's done, but when to present it is up to the secretary-general."
The two diplomats said the inspectors had soil, blood and urine samples and may also have collected remnants of the rockets or other weapons used in the attack, which could point to those responsible. The diplomats spoke on condition of anonymity because discussions on the issue have been confidential.
Haq said after receiving the report, Ban will present it U.N. member states and that the media should receive it shortly afterward.
In his speech, Ban said "the disaster" in Syria has created "a lost generation of children and young people" and led to "rising sectarian tensions, regional instability, the largest displacements of people in a generation, grave violations of human rights, including sexual violence."
"The latest fighting has also raised the specter of chemical warfare — which, if confirmed by the U.N. investigation mission, would be an atrocious violation of international law," Ban said.
