Abu Nidal Organization

The Abu Nidal Organization (ANO) is the most common name for the Palestinian nationalist militant group Fatah – The Revolutionary Council ("Fatah al-Majles al-Thawry"). The ANO is named after its founder Abu Nidal. It was created by a split from Yasser Arafat's Fatah faction of the PLO in 1974. The group has been designated as a terrorist organization by the United States, the United Kingdom, Japan, Israel, Canada, and the European Union.
The ANO was secular and anti-Western, but was not particularly associated with any ideology, or at least no such foundation was communicated. The organization was strongly linked with Abu Nidal's personal agenda. The group carried out hijackings, assassinations and kidnappings of diplomats, and attacks on synagogues – 90 attacks during the period 1974–1992. Nidal died in Baghdad in 2002.
Formation and background.
The Abu Nidal Organization was established by Sabri Khalil al-Bannah (Abu Nidal), a Palestinian Arab nationalist and a former Ba'ath party member. Al-Bannah established his faction within the PLO, just prior the Black September in Jordan, and following internal disagreements within the PLO. During Fatah's Third Congress in Damascus in 1971, he emerged as the leader of a leftist alliance against Yasser Arafat. 
Abu Nidal's first independent operation took place on September 5, 1973, when five gunmen using the name "Al-Iqab" ("The Punishment") seized the Saudi embassy in Paris, taking 11 hostages and threatening to blow up the building if Abu Dawud was not released from jail in Jordan, where he had been arrested in February 1973 for an attempt on King Hussein's life. Following the incident, Mahmoud Abbas of the PLO took flight to Iraq to meet Abu Nidal. In the meeting Abbas became so angry, that he stormed out of the meeting, followed by the other PLO delegates, and from that point on, the PLO regarded Abu Nidal as a mercenary.
Two months later, just after the October 1973 Yom Kippur War, during discussions about convening a peace conference in Geneva, the Abu Nidal Organization (ANO) hijacked a KLM airliner, using the name of the Arab Nationalist Youth Organization. The operation was intended to send a signal to Fatah not to send representatives to any peace conference. In response, Arafat officially expelled Abu Nidal from Fatah in March 1974, and the rift between the two groups, and the two men, was complete. In June the same year, ANO formed the Rejectionist Front, a political coalition that opposed the Ten Point Program adopted by the Palestine Liberation Organization in its 12th Palestinian National Congress session.
Abu Nidal then moved to Ba'athist Iraq where he set up the ANO, which soon began a string of terrorist attacks aimed at Israel and Western countries. Setting himself up as a freelance contractor, Abu Nidal is believed by the United States Department of State to have ordered attacks in 20 countries, killing or injuring over 900 people. The ANO group's most notorious attacks were on the El Al ticket counters at Rome and Vienna airports in December 1985, when Arab gunmen high on amphetamines opened fire on passengers in simultaneous shootings, killing 18 and wounding 120. Patrick Seale, Abu Nidal's biographer, wrote of the attacks that their "random cruelty marked them as typical Abu Nidal operations."
ANO attacks.
The ANO carried out attacks in 20 countries, killing or injuring almost 1,650 persons. Targets include the United States, the United Kingdom, France, Israel, moderate Palestinians, the PLO, and various Arab and European countries. The group has not attacked Western targets since the late 1980s.
Major attacks included the Rome and Vienna Airport Attacks in December 1985, the Neve Shalom synagogue in Istanbul and the Pan Am Flight 73 hijacking in Karachi in September 1986, and the "City of Poros" day-excursion ship attack in Greece in July 1988.
The ANO has been especially noted for its uncompromising stance on negotiation with Israel, treating anything less than all-out military struggle against Israel as treachery. This led the group to perform numerous attacks against the PLO, which had made clear it accepted a negotiated solution to the conflict. Fatah-RC is believed to have assassinated PLO deputy chief Abu Iyad and PLO security chief Abul Hul in Tunis in January 1991. It assassinated a Jordanian diplomat in Lebanon in January 1994 and has been linked to the killing of the PLO representative there. Noted PLO moderate Issam Sartawi was killed by the Fatah-RC in 1983. In the late 1970s, the group also made a failed assassination attempt on the present Palestinian president and PLO chairman, Mahmoud Abbas. These attacks, and numerous others, led to the PLO issuing a death sentence "in absentia" against Abu Nidal. In the early 1990s, it made an attempt to gain control of a refugee camp in Lebanon, but this was thwarted by PLO organizations.
Internal torture and executions.
The ANO's official newspaper "Filastin al-Thawra" regularly carried stories announcing the execution of traitors within the movement. Each new recruit of the ANO was given several days to write down his life story and sign a paper agreeing to his execution if anything was found to be untrue. Every so often, the recruit would be asked to rewrite the whole story. Any discrepancies were taken as evidence that he was a spy and he would be made to write it out again, often after days of being beaten and nights spent forced to sleep standing up. 
By 1987, Abu Nidal used extreme torture tactics on members of the ANO who were suspected of betrayal and disloyalty. The tactics included hanging prisoners naked, whipping them until unconsciousness, using salt or chili powder to revive them, forcing them into a car tire for whipping and salt application, melting plastic on their skin, frying their genitals, and confining them in tiny cells bound hand and foot. If cells were full, prisoners might be buried alive with a steel pipe for breathing. Execution was carried out by firing a bullet down the pipe. 
From 1987 to 1988, hundreds of members of Abu Nidal's organization were killed due to internal paranoia and terror tactics. The elderly wife of a veteran member was also killed on false charges. The killings were mostly carried out by four individuals: Mustafa Ibrahim Sanduqa, Isam Maraqa, Sulaiman Samrin, and Mustafa Awad. Decisions to kill were mostly made by Abu Nidal after he had consumed a whole bottle of whiskey at night. According to ANO dissidents, the attacks made by the group were unconnected to the Palestinian cause and led to their defection. In addition, they claimed the guerrilla was the "living example of paranoia".
