The report said it had identified 19 suspects but did not name them. It said five Syrian officials questioned by U.N. investigators in Vienna this month were suspects.
It complained that Damascus was trying to cast doubt on the investigation's findings, and said it had asked to interview a sixth Syrian official, also considered a suspect, but that session had to be postponed.
"This was, at the least, an attempt to hinder the investigation internally and procedurally," it said.
The report said statements made by two of the Syrian suspects "indicated that all Syrian intelligence documents concerning Lebanon had been burned".
