"Every complaint merits an investigation," the spokesman told AFP news agency on Friday when asked whether a probe had been launched into Mazlum-Der's  complaint.
  
Under Turkish law, prosecutors are obliged to look into all complaints to determine whether there are grounds to initiate a full-scale investigation that could lead to formal charges.
 
If the prosecutor decides the complaint does not merit a case, it will be dismissed.

'Genocide'
  
In its petition, Mazlum-Der accused Israel of carrying out "direct attacks on civilians with the aim of annihilating them" and employing internationally-banned weapons in the process.
  
"The suspects, who wanted to wipe out the Palestinian people through systematic attacks, have committed genocide and crimes against humanity," it said, demanding that the suspects be detained if they enter Turkey.
  
Turkish law allows for the trial of people accused of genocide or crimes against humanity even if the crimes were committed abroad.
  
Israel's 22-day offensive last month on Hamas-controlled Gaza left more than 1,300 Palestinians dead and injured 5,300 others.

Turkey, one of the few Muslim allies of Israel, strongly criticised the assault on Gaza  amid almost daily anti-Israel demonstrations across the country.
