Israeli security forces stormed the Mavi Marmara in international waters on Sunday night as it ferried 500 unarmed protesters towards Gaza.
The assault killed nine and injured dozens more, sparking worldwide condemnation.
Israel attempted to claim that its shock troops acted in self-defence after coming under attack, blaming the protesters for provoking the situation and being "terrorist supporters."
But Professor Hafidzudin told the Astro Awani reporters: "This was a peaceful humanitarian mission in international waters. The youngest person on board was not yet one, the oldest was 88 years old.
"We had no weapons on board. The Israelis are displaying knives taken from the kitchen. People did defend themselves with whatever was at hand.
"The attack started with percussion grenades and we feared they would use tear gas. The Israeli commandos attacked from all sides and began shooting almost immediately, initially with so-called rubber bullets but certainly within two or three minutes we heard the unmistakable sound of live rounds.
"A colleague from Viva Palestina , Nicci Enchmarch, was next to a Turkish man who was holding a camera. He was shot through the middle of the forehead. The exit wound blew away the back of his skull and she cradled him in her arms as he died."
At least four of those killed were shot through the head, he said.
"Where people had been sleeping was turned into a makeshift triage area. This turned into a makeshift mortuary. Despite repeated requests the Israeli forces refused to evacuate any of the injured for more than an hour.
The brutality and degradation continued throughout their ordeal only improving slightly when the British consular official arrived at the prison.
this is a violation of human rights in blatant
and also shows the actual crossing of the Jews....
in my view, the only way to fight the Jews is .. especially the Muslim countries must unite forces to ensure that Muslims in Palestine have a defense against the misery which they suffered for over 100 years.....
