IDFs clarifies earlier radio transmission between navy and Flotilla

Recently the IDF distributed a video in which "Peace activists" tell Jews to go back to Auschwitz. Many (including myself) were questioning the authenticity of this video and believed the IDF fabricated this video because of other possible known facts:

On hearing the recording Adam Shapiro, co-founder of the International Solidarity Movement, identified the woman's voice as that of his wife Huwaida Arraf, chair of the Free Gaza Movement. However, Arraf was not aboard the Mavi Marmara. She was aboard one of the small passenger vessels in the six-boat flotilla, called Challenger 1.

The IDF spokesperson clarifies now:

"the audio was edited down to cut out periods of silence over the radio as well as incomprehensible comments so as to make it easier for people to listen to the exchange. We have now uploaded the entire segment of 5 minutes and 58 seconds in which the exchange took place and the comments were made.

This transmission had originally cited the Mavi Marmara ship as being the source of these remarks, however, due to an open channel, the specific ship or ships in the “Freedom Flotilla” responding to the Israeli Navy could not be identified. During radio transmissions between Israeli Navy and the ships of the “Free Gaza” Flotilla on 31 May 2010, the Israeli Navy ship attempts to make contact with the ‘Defne Y’ on channel 1-6. Other ships from the flotilla respond on the channel, without identifying themselves. At some point during the radio exchange the Israeli Navy is told by one of the ships to “shut up, go back to Auschwitz” (2:05) and “don’t forget 9-11″ (5:42)."

Here it is, the unedited version:

UPDATE: Defne Y is a cargo ship and it was one of the ships of Flotilla which came from Turkey.
