Arafat Jaradat’s autopsy showed torture, while his heart was in good condition, PA Minister of Detainee Affairs said Sunday, according to Maan news agency.

A spokeswoman for Israel’s Prison Authority said Saturday that Jaradat had apparently died of cardiac arrest in Megiddo prison. The spokesman added that the injuries found in the autopsy could have been caused by the medical emergency team’s efforts to resuscitate Jaradat.

The 30-year-old man from Sair near Hebron in the occupied West Bank was arrested last Monday for alleged involvement in a November 2012 stone-throwing incident that injured an Israeli, according to Israel’s Shin Bet domestic intelligence service, Al Jazeera reported.

Several thousand Palestinian prisoners held by Israel observed a one-day fast to protest Jaradat’s death.

It’s worth noting that over 207 Palestinian prisoners died in Israeli jails. Many of them were killed under torture and medical negligence. At the moment a number of prisoners are on a hunger strike.

“It’s widely known that Israel one of the top countries that constantly violates International laws. Yet, this fact did not drive an International action or pressure. Torture continued to be an integral part of the policy of this state. Meanwhile, no inspection against these prisons was carried out. There were also no reports that denounced what Israelis have been doing over the past decades.” UFree to defend the rights if Palestinians said.

UFree also expressed its fear over the health conditions of many Palestinian prisoners as Israel is medically neglecting their basic needs. It also calls on International organisations like the Red Cross, Amnesty and others to reveal all illegal practices committed by Israel and escalate them to the United Nations and the international community and European Union bodies.
