Former Meretz leader Yossi Sarid told the Egyptian daily al-Ahram that the execution of Egyptian captives by Israeli soldiers at the end of the Six Day War in 1967 was a war crime.
Israel's Channel One television aired a documentary earlier this week in which it was claimed that an elite Israeli army unit commanded by Labor MK Benyamin Ben-Eliezer executed 250 unarmed Egyptian soldiers.
"The killing of Egyptian captives in the Six Day War was a war crime … but the problem in the region is that war crimes are numerous," the newspaper quoted Sarid as saying on Saturday.
The claims made in the documentary received intensive media coverage in Egypt.
Sarid told the newspaper that although he had not seen the documentary he was aware that Israeli soldiers had committed war crimes against Arab soldiers during the Six Day War.
"Punishing those behind those crimes 40 years after the 1967 war is difficult but history will judge those people," Sarid told al-Ahram.
Israeli-Egyptian relations were strained three years ago when the Egyptian Foreign Ministry raised the possibility of demanding that Israel paid compensations for Egypt for the alleged killings.
