PARIS (AFP) A French judge probing a Pakistan bomb attack that killed 11 French engineers has asked Britain and Switzerland to provide whatever information they have on allegations of embezzlement by President Asif Ali Zardari, legal sources here said Friday. Judge Marc Trevidic made the request to help him advance his probe into claims that 11 French engineers were killed in May 2002 by Pakistani agents taking revenge after a new French government cancelled illegal commissions on an arms deal. Last month families of victims filed suit in Paris against supporters of former French presidential candidate Edouard Balladur, who was prime minister at the time, alleging they benefited from the deal. In 1995, newly elected president Jacques Chirac cancelled the pay-offs, which he believed had funded his rivals campaign, angering Pakistani officers awaiting their share of the graft, according to a report commissioned by Frances state naval construction firm and leaked last June. The families believe they were deceived by the French state and top ranking French and Pakistani political leaders, and that their loved ones were exposed and killed as a result of a sordid political funding scandal. One leaked French report on the affair said that the commissions paid to Pakistani figures were ordered by Zardari. Zardari spent 11 years in jail on charges ranging from corruption to murder. In all, 14 people were killed on May 8, 2002, when a suicide bomber attacked a bus carrying French naval engineers from their Karachi hotel to where they were working on the submarines sold to Pakistan in the suspect deal. At first, officials in both countries blamed radicals at war with the West for carrying out the attack, but French counter-terrorism officers have begun privately to accuse Pakistani spies of ordering it.
