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.
The U.N. chief made the comment shortly before the chief chemical weapons inspector, Ake Sellstrom, told The Associated Press that he has completed his report and will deliver it to Ban in New York this weekend.
Ban also said that 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," Ban said.
The secretary-general thought his speech to the Women's International Forum and response to questions were not being broadcast, but they were shown on U.N. television.
