The relevant thing in any case would not be whether those killed were members of this or that, but whether they were engaged in terrorist activity when they were killed.

This was planned and organised as an essentially non-violent demonstration. The fact that all those killed and virtually all those injured were Arabs is evidence that those taking part stuck to that pretty well. No doubt there will have been many members of Hamas and other organisations who will have taken part in it. I am reminded of Bloody Sunday when the IRA issued strict orders that guns should not be taken by any IRA supporters who took part.
