The Palestinian prisoner Yasser Ashtiyeh from Nablus died Friday evening in Beersheba prison south of Israel.

Local and media sources reported that the 36-year-old Palestinian prisoner was found dead in his prison cell.

In a separate statement the Palestinian Health Ministry affirmed Ashtiyeh has died due to “deliberate medical negligence.”

Ashtiyeh was detained in 2009 and sentenced to life for being involved in an Israeli settler’s killing.

Earlier Wednesday the prisoner Fares Baroud died in Israeli custody of the health complications he developed in Israeli jails due to medical negligence.

Palestinian prisoner in Israeli jails Wesam Shalaldeh 28 was announced dead in mysterious circumstances on Friday according to the Palestinian Prisoner Society.
