Ramallah, Occupied West Bank - The condition of a Palestinian prisoner on hunger strike has deteriorated seriously, an advocacy group said Sunday.

Khader Adnan “suffers from serious health conditions characterised by severe weight loss, severe wasting and vomiting blood”, the Palestinian Prisoners’ Club said.

Adnan, who has carried out a series of previous hunger strikes in Israeli captivity, was rearrested by the Israeli regime in December over his involvement with the Islamic Jihad organisation.

He rejected the accusations and began a hunger strike on September 2, the prisoners’ club said.

Adnan is expected to appear in court on Monday, it added.

There was no immediate response from the Israeli side.

In 2012 Adnan went on hunger strike for 66 days in protest against his administrative detention, and in 2015 he again went on strike for 54 days after another arrest.
