A Palestinian prisoner from the Shejaiya neighborhood in the Gaza Strip died from torture he endured at the Sde Teiman detention center, a pair of prisoners affairs groups said, Anadolu Agency reports.

Islam al-Sarsawi, 42, was arrested during a recent Israeli raid at the Al-Shifa Hospital. He died from torture at the Sde Teiman Israeli military camp, the Commission of Detainees’ Affairs and the Palestinian Prisoners Society said in a statement.

“Al-Sarsawi is among dozens of detainees who have lost their lives in Israeli prisons and detention camps. The Israeli authorities continue to conceal their identities,” it added.

The Israeli military previously stormed the Al-Shifa Medical Complex twice — Nov 16, following a week-long siege, and in March. The latter operation left the vital medical facility in ruins, resembling a mass grave.

The statement clarified that al-Sarsawi died in March but recent information confirmed his fate.
