The family of a Palestinian prisoner held by Israel says his health is dire after waging a hunger strike for the last 56 days.
Naser Allan says Israel arrested his son, Mohammed, in November 2014 and placed him under administrative detention for two six-month periods. He says his son was imprisoned from 2006-2009 for affiliation with the Palestinian militant group Islamic Jihad.
The younger Allan is on hunger strike to protest his administrative detention, a controversial measure that allows Israel to detain suspects without charge for long periods.
Allan's father said Sunday that Israeli authorities are threatening to force-feed his son. Allan has refused medicine or vitamins, only drinking water.
A contentious Israeli law passed last month permits the force-feeding of inmates on a life-threatening hunger strike.
