Yair Klein (; also known as Jair Klein) is a former lieutenant colonel in the Israeli army, who established a private mercenary company called Spearhead Ltd. Through Spearhead Ltd, Klein provided arms and training to armed forces in South America, Lebanon, and Sierra Leone. Klein and his company were accused of training the death squads of drug traffickers and right-wing militias in Colombia in the 1980s. He was convicted by judicial authorities in Colombia for training several members of Colombian paramilitary groups and the militias of drug traffickers, including Gonzalo Rodríguez Gacha and Pablo Escobar Gaviria. The Colombian government made unsuccessful attempts to obtain his extradition from Israel. In a 2007 interview with Caracol TV, Klein claimed that he was sent to Colombia by request of the National Police in order to train its members, and stated that he was willing to go back and help destroy the FARC guerrillas. He also criticized the demobilization of the paramilitaries, saying it was "stupid" to do so while the guerrillas remained a threat. Guns for Antigua Klein, with the help of Bruce Rappaport, was heavily involved in the Guns for Antigua scandal of 1989, helping Maurice Sarfati launder guns from Israel through Antigua to Colombia, intending to supply Israeli-made weapons to the Medellin Cartel. He was also intended to run the training school for mercenaries that was to be set up on Antigua through which the guns were to be laundered, however, the plan was exposed before this could be set up. Klein was put on trial for three counts of exporting military equipment and expertise without the requisite licenses at the Jerusalem Magistrate's Court. Klein pleaded guilty and was convicted in late November 1990. During the trial, he explained that he pleaded guilty "to put an end to the witch hunt running rampant in some of the press, based on rumours and speculation which are harming the state and me." He claimed he had acted "in good faith and in the belief that my actions were within the law.
