Anger is building up among Palestinians held in Israeli prisons, with several inmates on long-running hunger strikes in a number of prisons and clashes erupting in the Nafha jail in southern Israel.
Rights groups have warned that the health of a hunger-striking jailed Palestinian has plummeted as his fast hits 51 days.
Sami Janazrah, 43, launched his hunger strike on March 3 to protest against being held in solitary confinement and administrative detention, a practice in which Israel jails Palestinians on "secret evidence" without charges or trial.
Janazrah, who is a married father of three from the al-Fuwwar refugee camp in Hebron, is reportedly suffering from low blood pressure and arrhythmia, causing seizures and fainting spells. Meanwhile, his weight has sunk to 52 kilogrammes.
