Vittorio Arrigoni, who is being beatified as a new Palestinian Arab saint as I write this, was not the first ISM activist to be murdered by his fellow Palestinian Arabs.
In September 2007, ISM member Akram Ibrahim Abu Sba’ was killed by members of Islamic Jihad. He was shot twice in the chest in Jenin.
His killing was never condemned by the ISM. They know better than to say anything bad about Islamic Jihad, their erstwhile partners in "resistance" against Israel.
