A court in Istanbul is to try in absentia four ex-Israeli military commanders over the deadly raid of a Turkish boat as it tried to break the blockade of Gaza in 2010.
Nine Turkish activists died in clashes after the Israeli commandos boarded the Mavi Marmara. Seven of the commandos were also wounded.
The incident led to a major rift in relations between Turkey and Israel.
If the four are convicted, the court could issue a warrant for their arrest.
The accused are former Israel army chief of staff Gen Gabi Ashkenazi, ex-naval chief Vice Admiral Eliezer Marom, former head of military intelligence Maj Gen Amos Yadlin, and former head of the air force Brig Gen Avishai Lev.
