Israeli prison guards fired tear gas to quell disturbances by Palestinian inmates after a prisoner serving a life sentence over an attempt to bomb an Israeli cafe died of cancer.

Maysara Abu Hamdeya's death yesterday threatened to raise tensions in the Israeli-occupied West Bank, where Palestinians, who view jailed brethren as heroes in a fight for statehood, have held several protests in recent weeks in support of prisoners.

Palestinian President Mahmoud Abbas said Israel had ignored long-standing pleas to free Abu Hamdeya, 64, sentenced to life in prison in 2002 for recruiting a bomber who planted explosives in a Jerusalem cafe. The bomb did not detonate.

A Prisons Service spokeswoman said Abu Hamdeya died in a hospital in southern Israel yesterday before an early release process, begun last week after doctors diagnosed his cancer as terminal, could be completed.

Mr Abbas said: "The Israeli Government in its intransigence and arrogance refused to respond to Palestinian efforts to save the life of the prisoner."

Abu Hamdeya is the second Palestinian to die in Israeli custody this year. Arafat Jaradat, 30, died after an interrogation session in February. Palestinian officials said he had been tortured, an allegation Israel denied.

News of Abu Hamdeya's death touched off protests by Palestinian inmates in several Israeli prisons. At Ramon jail, in southern Israel, inmates threw objects at guards, who responded with tear gas.

Three prisoners and six guards were treated at the jail for tear gas inhalation.

In Abu Hamdeya's West Bank home city of Hebron, masked demonstrators clashed with Israeli soldiers. No serious injuries were reported.

Some 4800 Palestinians are held in Israeli jails. Israel says most of them planned or carried out anti-Israeli attacks.

It also holds 178 "administrative" detainees who have been jailed without trial as suspected militants for renewable three to six-month terms based on classified evidence.
