JENIN (Ma'an) -- A Palestinian detainee entered his sixth day on hunger strike on Friday in solidarity with prisoner Hana Shalabi, a detainees' center said.

Jafar Abu Salah, 45, was detained by Israeli forces from his home in Arraba village in the northern West Bank. Israeli courts have postponed his hearing 11 times, the center said.

Abu Salah has been detained by Israel four times.

The prisoner started the hunger strike, despite suffering health and stomach problems, in solidarity with Shalabi, a 29-year-old detainee who has refused food for 30 days.

Shalabi has been held in an Israeli jail without charge or trial since Feb. 16. She is now suffering spells of dizziness, muscular wasting and loss of consciousness, her lawyers and medical observers say.
