The Black September Organization was established by Fatah members in 1971 for reprisal operations and international strikes after the September events . On 28 November 1971 , four of the group 's members assassinated Prime Minister Wasfi Tal in the lobby of the Sheraton Cairo Hotel in Egypt while he was attending an Arab League summit .

Fatah has always publicly denied its responsibility for Black September operations , but by the 2000s , some high-ranking Fatah and Black September officials acknowledged the relationship
