Carla del Ponte, a former war crimes prosecutor, and a member of the UN commission investigating possible war crimes in the Syrian civil war, has given an interview stating that there was evidence that the Syrian rebels may have used chemical weapons.

Yes, you heard right, she has suggested that the rebels, not the government, might have been using chemical weapons:

A leading member of a United Nations investigatory commission says there are “strong concrete suspicions but not yet incontrovertible proof” that Syrian rebels have used the nerve agent sarin.

Carla del Ponte, a former prosecutor for U.N. tribunals investigating war crimes in the former Yugoslavia and Rwanda, made the comment in an interview Sunday with a Swiss television channel, the BBC reported.

The U.N. panel, known as the Independent International Commission of Inquiry on Syria, emphasized in a statement Monday that it had reached no conclusions about the possible use of chemical weapons in Syria’s civil war.

“I was a little bit stupefied by the first indications we got … about the use of nerve gas by the opposition,” Del Ponte told Swiss Italian broadcaster RSI.

She said the evidence emerged from interviews conducted by investigators with victims, physicians and others in neighboring countries.

Del Ponte did not rule out the possibility that President Bashar Assad’s government may also have used chemical agents on the battlefield.

The official response from the UN was to deny this:

U.N. war crimes investigators have reached no conclusions on whether any side in the Syrian war has used chemical weapons, the inquiry commission said on Monday, playing down a suggestion from one of the team that rebel forces had done so.

Investigator Carla Del Ponte caught U.N. officials by surprise on Sunday when she said the commission had gathered testimony from casualties and medical staff indicating that rebel forces had used the banned nerve agent sarin.

“The independent international Commission of Inquiry on the Syrian Arab Republic wishes to clarify that it has not reached conclusive findings as to the use of chemical weapons in Syria by any parties to the conflict,” it said in a statement.

It seems to me that something odd is going on.

Certainly, it is not outside of the realm of possibility for the rebels to have deployed Sarin, after all, a significant portion of their arsenal used to be the Syrian government’s arsenal.

Why someone like Carla del Ponte would make a public statement like this is not clear to me, particularly since since, by her own admission, the evidence is sketchy.

I’m wondering if this is push-back against pressure to make a definitive statement against the Assad government.

Certainly commiseration’s response to her statement would indicate that if there was any move to early judgement, there isn’t now.

Maybe it’s an honest mistake, but I sounds like some weird sort of wheels within wheels stuff.
