Concurrent with the execution of four Iranians in Saudi Arabia, and despite warnings by human rights activists and institutions, four Ahwazi Arab prisoners—Taha Heidarian, Abdolrahman Heidarian, Abbas Heidarian, and Ali Sharifi—were secretly executed by the Iranian authorities. The prisoners—three of them brothers—were arrested following civil unrest and protests in April 2011 in Ahwaz (capital of the southwestern Iranian province of Khuzestan).
