Former Palestinian prisoner Jaafar Ibrahim Awad, 22, died on Friday after developing health complications while serving time in an Israeli jail, medics said.

Awad was released from Israeli custody three months ago after his health rapidly declined and was moved to an intensive care unit this week.

Doctors at al-Mizan hospital in Hebron pronounced him dead at 2:45 a.m. on Friday, Maan news agency reported.

Awad suffered from severe pneumonia, heart problems, and thyroid and pancreas complications. Israeli authorities had agreed to release Awad only after the director of the Prisoners' Society's legal department submitted an appeal. Awad was from Beit Ummar in northern Hebron, and spent a total of three years in Israeli jails, most recently detained in November 2013.

The Palestinian Prisoners Society in Hebron held the Israeli government responsible for his death. His funeral will take place after Friday prayers.
