Hanin Zoabi is a not only an Israeli citizen, she's a member of Israel's Knesset. She was also on that Turkish ship, from the Turkish side, not the IDF side. Since she has immunity she hasn't been arrested and is free to give interviews to the media. According to Haaretz in Hebrew, she's telling that there were at least three dead civilians on the Mavi Marmara even before the first IDF troops came aboard, from advance fire. She personally saw the bodies.
I'm putting this up because it speaks to the willingness to stand in front of a camera and brazenly lie though one's teeth. Something to keep in mind.
