Thousands of security prisoners in Israel's jails sent back their food on Sunday morning, in a show of solidarity with Palestinian hunger strikers in Israel's jails as Palestinians clashed with security forces in the West Bank.

Security forces were on high alert in the West Bank and east Jerusalem on Sunday morning amid concerns that the death of Palestinian prisoner Arafat Jaradat in Megiddo Prison on Saturday would set off violent Palestinian demonstrations.

The Palestinian Authority on Saturday strongly condemned Jaradat's death from an apparent heart attack and called for a UN investigation into the case.

There were demonstrations in Ramallah and Hebron following his death and 4,500 Palestinians in Israeli prisons sent back there food Sunday morning in protest.

Israel Prison Service spokesman Sivan Veitzman said the protest includes nearly all of the security prisoners in Israel's jails but that the IPS does not view the action as a hunger strike and that they expect that the protest will only last one day, at most three.

She added that while the protest has not included violence on the part of any of the security prisoners, prison personnel are currently on a higher state of alert than usual.

In Jaradat's village of Kfar Sa'ir near Hebron, dozens of Palestinians threw stones at IDF soldiers on Sunday morning. Riots were reported in additional areas of the West Bank, mostly in the Hebron area.

The IDF employed riot dispersal methods in attempts to contain the rioters.

Jaradat's death came amid heightened tensions as a group of security prisoners in Israeli jails engage in an ongoing hunger strike. Even before Jaradat’s death, Palestinians rioted and attacked security personnel in several places in the West Bank and in east Jerusalem on Friday.

Police are investigating the death and an autopsy was set for Sunday.

PA Minister for Prisoners Affairs Issa Qaraqi held Israel fully responsible for the death of Jaradat and charged that he had been tortured.

Qaraqi and PLO Executive Committee member Hanan Ashrawi called on the UN to open an investigation into the death of Jaradat.

“This is not an isolated case,” Ashrawi said, referring to the death of the inmate.

“This is the case of the rights of all the prisoners – rights that are being violated by the occupation. This requires quick action to open Israeli prisons to the world.”

Ashrawi said the Palestinians were determined to demand that the UN Security Council force Israel to honor the rights of Palestinian prisoners.

Contributing to the tense atmosphere in the West Bank were clashes between settlers and Palestinians on Saturday.

The IDF is investigating the possibility that Israeli civilians shot two Palestinians from Kusra, near Nablus, during clashes with settlers and the IDF on Saturday.

Aron Katsof, a spokesman for the Esh Kodesh outpost, said that Palestinians attacked his small community around noon by throwing stones and that he and others from the outpost and nearby settlements went out to defend their homes. He denied that anyone had shot at the Palestinians.

Rabbis for Human Rights said the Palestinians were shot in Kusra. The organization’s field worker Zacharia Sadeh charged that violence broke out after settlers had attacked two homes in the village.
