Erdogan made the comment during a campaign speech Saturday in the Black Sea port city of Ordu. He is running for the presidency in elections next month.
He has been speaking out strongly against Israel during its offensive against Hamas militants in Gaza, which has killed more than 300 Palestinians. He accuses Israel of using disproportionate force and has said the operation there has derailed efforts to normalize Turkish-Israeli ties. Those soured after Israel's 2010 raid on an aid ship which killed eight Turks and a Turkish-American.
Hundreds have also staged protests in recent days outside Israeli diplomatic mission in Ankara and Istanbul.
