The Turkel Commission (officially The Public Commission to Examine the Maritime Incident of 31 May 2010) is an inquiry set up by Israeli Government to investigate the Gaza flotilla raid, and the Blockade of Gaza. It is led by Israeli retired Supreme Court Judge Jacob Turkel. The other initial members of the commission were former President of the Technion and military expert, Amos Horev, and professor of international law, Shabtai Rosenne, who died in September 2010. The probe was overseen by two International observers: William David Trimble, former Leader of the Northern Irish Ulster Unionist Party and Northern Irish First Minister, a Nobel Peace Prize laureate, and Canadian former military judge Ken Watkin.
