Sabri Khalil al-Bana, known as Abu Nidal, is considered the founder and one of the most prominent leaders of the Fatah (PLO) organization for the liberation of Palestine before its split and the establishment of the Fatah Revolutionary Council - in 1974.

Abu Nidal was born on May 16, 1937 in Jaffa. He joined the Ba'ath party in 1955 and then joined the movement led by Yasser Arafat in 1967, and he first took over the organization's regional security leadership in Jordan, and in 1969 became Fatah's representative in Sudan, before being appointed head of the PLO ministry in Baghdad.

Abu Nidal was accused of being responsible for the killing and wounding of hundreds during manyh terrorist attacks in the 1970s and 1980s in a number of countries, including the United States, Britain, France, Israel, Arab countries and even the Palestinians.

In 1982, the organization carried out a grenade attack on the Joe Golandenberg restaurant in the Paris ghetto, killing six people and wounding 22 others.

Former French intelligence chief Yves Bonnie admitted in 2019 that Paris had struck an oral agreement with Abu Nidal in the 1980s, stipulating that the French authorities would not attack members of his organization in exchange for not carrying out operations on its territory.
