It would make sense, of course, to deflect the shame of it all. The fact that there remains some mystery only allows for the water to be muddied by those who might wish to do so.
In any case, it was certainly a vile act of censorship and it was most probably (and most sadly) comitted by a Palestinian.

Naji Salim al-Ali, 46, unquestionably the best-known Arab political cartoonist was gunned down on July 22, 1987, at broad daylight on a London street. The shooting was witnessed by hundreds of people during rush hour, but the assailant was able to escape, and to date, the Scotland Yard was not able to conclusively solve the case. After shooting al-Ali in the head at close range, the gunman swiftly walked to a car and drove away. Although Police gave him a high-speed chase, the assassin escaped. Speculations have been widely focusing on two scenarios: a. al-Ali angered Yassir Arafat with a cartoon about one of his alleged mistresses and ordered the cartoonist’s assassination; b. Mossad, the Israeli secret service, arranged the liquidation of the cartoonist who drew many effective anti-Israeli cartoons. Al-Ali had received over 100 death threats from a wide variety of sources before he was killed. Very few regimes and groups in the Middle-East escaped his biting commentary. He condemned war and religious fanaticism, opposed Palestinian accesses as much as the Israeli occupation, and passionately advocated human rights. A few years before his murder he was quoted as saying: “I never felt fear, failure, or despair… I face armies with cartoons.”

Ten months after Naji al-Ali was shot, Scotland Yard arrested a Palestinian student who turned out to be a Mossad agent. Under interrogation, the Jerusalem-born man, Ismail Suwan, said that his superiors in Tel Aviv had been briefed well in advance of the plot to kill the cartoonist.

By refusing to pass on the relevant information to their British counterparts, Mossad earned the displeasure of Britain, which retaliated by expelling two Israeli diplomats from London. A furious Margaret Thatcher, then prime minister, closed Mossad’s London base in Palace Green, Kensington. Undeterred by the British reaction, Mossad used forged passports of another Western government to send its agents to Tunisia to lay the groundwork for the assassination of Abu Jihad.

Israel and Britain had been in contact for several months via diplomatic channels concerning Suwan’s revelations that he had worked with the Mossad. Newspapers reported that the action was partially a result of accumulating British grievances against the Mossad, including the abduction of Mordechai Vanunu and the use of British passports, found in a phone booth in West Germany in 1987. However, despite the arrests by Scotland Yard and an investigation by MI5, the assassin’s identity has never been revealed.

he was assasinated probably because of a cartoon mocking rashidah mohran and he possible relationship with yaser arafat, a relationship that was not directly related to liberating palestine !

i’m just thinking now, am i at risk of assasination now ? :D

Mohd Tahboub,

It is the crudest variety of censorship, not unlike what happened to the director, Theo van Gogh who was murdered by Moslem radicals in 2004.

It’s probably impossible to know the exact cartoon that triggered the muder. But such a cartoon might not exist, really.
A persuasive theory is that he was likely killed for his history of criticising Palenstinian leadership. But, of course, we are unlikely to ever know for sure.

Thank you,
Moh’d
