JERUSALEM: Khader Adnan, who was affiliated with the Palestinian militant Islamic Jihad group, died in an Israeli prison on Tuesday after an 87-day hunger strike, Israeli prison authorities said.

Israel said Adnan "refused to undergo medical tests and receive medical treatment" and "was found unconscious in his cell" early on Tuesday morning.

Adnan, 45, originally from the occupied city of Jenin, was a known figure in the West Bank, which was captured by Israel in a 1967 war.

Adnan had been in and out of detention and had undertaken five hunger strikes since 2004. (Reporting by Emily Rose, Nidal Al Mughrabi; Editing by Kim Coghill and Lincoln Feast.)
