Palestinian hunger striker dies in Israeli custody

STORY: A Palestinian Islamic Jihad leader died on Tuesday in Israeli custody after an 87-day hunger strike, authorities said.

Khader Adnan, who was awaiting trial, was found unconscious in his cell and taken to a hospital, where he was declared dead after efforts to revive him, Israel's Prisons Service said.

He had previously refused the service's medical care, it added.

Disputing the Prisons Service account, Adnan's lawyer Jamil Al-Khatib and a doctor with a human rights group who recently met him accused Israeli authorities of withholding treatment.

It's the first such fatality in more than three decades, and tensions around the Gaza Strip spiked as the Islamic Jihad swore revenge.

Hundreds of people took to the streets in Gaza to rally in support of Adnan and mourn his death, and the Israeli military said three rockets were fired into Israel from the strip.

In his hometown near Jenin, in the Israeli-occupied West Bank, Adnan's nine-year old son Ali led a protest march.

Carried on a man's shoulders Ali chanted: "Khader you are a hero" as Palestinian men chanted back.

There were no immediate claim of responsibility for the Gaza rockets reported by Israel.

Since 2011, Adnan had conducted at least three hunger strikes in protest at detentions without charges by Israel.

According to the Palestinian Prisoners Association, Adnan had been arrested by Israel 12 times, spending around eight years in prison, mostly under so-called "administrative detention" - or detention without charges.

Israel says such detentions are required when evidence cannot be revealed in court due to the need to keep intelligence sources secret.

Palestinians say they deny due process of law.

The Prisons Service said that this time, Adnan was arrested and indicted in an Israeli military court on charges that included links to an outlawed group and incitement to violence.
