 The former PKK commander Şemdin Sakık maintains the attack was part of the Doğu Çalışma Grubu's coup plans.Under the new Presidency of Süleyman Demirel and Premiership of Tansu Çiller, the Castle Plan (to use any and all means to solve the Kurdish question using violence), which Özal had opposed, was enacted, and the peace process abandoned.Some journalists and politicians maintain that Özal's death (allegedly by poison) along with the assassination of a number of political and military figures supporting his peace efforts, was part of a covert military coup in 1993 aimed at stopping the peace plans.
