The Free Gaza mailing list quotes a Ha'aretz article about the incident but prefixes it with "We all know the Israelis are inveterate liars, so I wouldn't assume any of it is actually true."
Since there were journalists on board, I am sure that a video will soon be available showing whether Israel fired at them. The CNN video report interviewing a CNN reporter on board says nothing about any shooting, only that the Israeli boat "rammed" the "Dignity." No doubt if there was any live fire, the CNN reporter would have mentioned it. Showing who the "inveterate liars" are.
The FGM freaks explicitly said yesterday in a press release that they will refuse to stop, no matter what:
We are not asking Israel for "permission" to go, and we will not stop until the DIGNITY lands in Gaza.
Just for context: The Free Gaza boat was supposed to have 3 tons of medical aid. During the past three days, Israel has sent 186 trucks filled with aid to Gaza - plus ten ambulances. Each truck, from past experience, holds between 10 and 20 tons of material.
Which means that for all the noise the FGM makes about how necessary their trip is to help Gazans, their "aid" equates to roughly 0.1% of what the hated, lying Zionist enemy has given while under direct attack from Gaza. Proving yet again that the off-key moonbats' purpose is not to help Gazans (they could coordinate sending aid through Israel, as Jordan does, or through Egypt, which sent 72 trucks of its own) but to hurt Israel through PR.
(I'm pretty sure that Israel's tractor trailers filled with aid are far larger than Egypt's.)
