Assessment: HIGHLY SUSPICIOUS​

Two detailed accounts published by Israeli journalists with intelligence sources attribute Haddad's death to Mossad poisoning. Aaron J. Klein's 2006 book Striking Back claims Mossad sent Haddad poisoned Belgian chocolates. Ronen Bergman's 2018 book Rise and Kill First provides a more detailed account involving poisoned toothpaste, replaced by a deep-cover Mossad agent on January 10, 1978. The toxin was allegedly developed at the Israel Institute for Biological Research. Israel has never officially confirmed or denied the operation. If the accounts are accurate, this assassination represents one of the most sophisticated and undetectable intelligence killings in recorded history.

Circumstances of Death​

In early 1978, Haddad began experiencing mysterious and rapid health deterioration. He was initially treated in Baghdad before being transferred to a hospital in East Berlin, where East German doctors diagnosed him with leukemia. According to intelligence reports, Haddad's condition deteriorated rapidly and agonizingly. According to an Israeli intelligence source in East Germany, Haddad's screams of pain were heard throughout the hospital ward, and he had to be heavily dosed with tranquilizers and sedatives. He died on March 28, 1978, approximately two and a half months after the alleged poisoning.

According to Ronen Bergman's account, on January 10, 1978, a deep-cover Mossad agent — identified only by the codename "Sadness" — who had gained a high level of access to Haddad's home and office, switched his regular tube of toothpaste for an identical tube containing a biological toxin developed at the Israel Institute for Biological Research in Ness Ziona. Some of the toxin penetrated the mucous membranes of his mouth and entered his bloodstream every time he brushed his teeth. The poison was designed to be slow-acting and to mimic the symptoms of a naturally occurring disease, specifically leukemia, making detection virtually impossible.

The Extraordinary Assassination Method​

The alleged poisoning of Wadie Haddad stands as one of the most remarkable assassination methods ever attributed to an intelligence service, for several reasons:

The delivery mechanism: According to the competing accounts, Mossad used either contaminated Belgian chocolates (Klein's version) or poisoned toothpaste (Bergman's version). The toothpaste method was particularly insidious — the target would self-administer the poison daily through normal hygiene, receiving small doses that accumulated over weeks.

The toxin design: The poison was allegedly developed at the Israel Institute for Biological Research at Ness Ziona, Israel's secretive center for chemical and biological weapons research. The toxin was specifically engineered to mimic leukemia symptoms — fatigue, weight loss, organ failure — making it undetectable by standard medical diagnostics. East German doctors, who had no reason to suspect poisoning, diagnosed naturally occurring leukemia.

The deep-cover agent: The operation required "Agent Sadness" to have sustained, intimate access to Haddad's personal belongings over a long period. This level of penetration into the inner circle of one of the world's most security-conscious militant leaders represented an extraordinary intelligence achievement. The agent had to identify Haddad's toothpaste brand, procure an identical tube, have it filled with the toxin, and switch it without detection.

The slow death: Unlike a bullet or a bomb, the poisoned toothpaste killed Haddad over approximately ten weeks. Each brushing delivered another dose. The gradual onset meant that by the time he sought medical attention, the damage was irreversible.

Two versions, one conclusion: The fact that two independent Israeli intelligence journalists — Klein and Bergman — provide different details about the delivery method (chocolates vs. toothpaste) but agree on Mossad responsibility suggests compartmentalized knowledge within Israeli intelligence. Different sources within Mossad may have known different aspects of the operation.

Background​

Wadie Haddad was a Palestinian Christian from Safed who co-founded the Popular Front for the Liberation of Palestine (PFLP) with George Habash in 1967. He became the PFLP's chief of external operations and was the mastermind behind some of the most audacious airline hijackings of the late 1960s and 1970s, including:

  • 1968: El Al Flight 426 hijacking to Algiers — the first hijacking of an Israeli aircraft
  • 1970: The Dawson's Field hijackings — the simultaneous hijacking of four Western aircraft to a remote Jordanian airstrip, an act that triggered the "Black September" civil war in Jordan
  • 1976: Air France Flight 139 hijacking to Entebbe, Uganda — which ended with the dramatic Israeli commando rescue operation on July 4, 1976

The Entebbe hijacking reportedly sealed Haddad's fate — Israel allegedly decided that a man capable of orchestrating such operations must be eliminated. He was expelled from the PFLP's political bureau in 1972 for conducting unauthorized operations, but continued independent operations under what became known as the PFLP-External Operations. He maintained relationships with multiple intelligence services: the KGB provided training and support, the Stasi provided safe haven in East Germany, and Iraqi intelligence provided operational support and base facilities.

Intelligence Connections​

  • Mossad allegedly recruited a deep-cover agent ("Sadness") with direct access to Haddad's personal spaces
  • The Israel Institute for Biological Research at Ness Ziona allegedly developed the specific toxin used
  • The poison was reportedly designed to mimic leukemia symptoms, making assassination undetectable
  • Haddad maintained contacts with multiple intelligence services: the KGB provided training, the Stasi provided safe haven, and Iraqi intelligence provided operational support
  • The Entebbe raid in July 1976 reportedly triggered the final decision to eliminate Haddad
  • Two competing accounts from Israeli intelligence journalists (Klein and Bergman) differ on the delivery method — chocolates vs. toothpaste — but agree on Mossad responsibility
  • The operation bears similarities to other intelligence poisonings, including the FSB's use of polonium-210 against Alexander Litvinenko (2006) and the Bulgarian secret service's ricin pellet attack on Georgi Markov (1978, the same year as Haddad's death)

Why This Death Raises Questions​

  • Two independent Israeli intelligence journalists, both with credible sources, attribute the death to Mossad poisoning
  • The accounts differ on the delivery method (chocolates vs. toothpaste), suggesting compartmentalized knowledge even within Israeli intelligence circles
  • Haddad's rapid health deterioration beginning in early 1978 is consistent with the January 10, 1978 poisoning date cited by Bergman
  • The alleged use of a slow-acting toxin designed to mimic natural disease represents a sophisticated assassination method that would be nearly impossible to detect
  • East German doctors diagnosed leukemia without apparently suspecting foul play, suggesting the toxin achieved its intended deception
  • The operation required a deep-cover agent with intimate access to Haddad's personal belongings — indicating long-term intelligence penetration
  • Israel has never confirmed or denied the operation
  • Reports of Haddad's extreme suffering — screams heard throughout the hospital — raise ethical questions even against a target with Haddad's record
