LARNACA, CYPRUS -- An Iranian opposition figure who arrived here from Sweden and was gunned down Aug. 26 was the third victim since June of an apparent assassination program that may have been approved at high levels in Tehran, according to Iranian opposition officials and Western specialists. Bahman Javadi, 33, a member of the central committee of the underground Iran Communist Party and its Komala Kurdish guerrilla forces, was shot in a hail of bullets fired by two men with silenced 7.65mm pistols. There have been no arrests, but Cypriot police believe the killing was politically motivated. A companion, Yussef Rashidzadeh, was hit in the chest and critically wounded. The Komala group, operating from bases in Iraq, has staged several attacks against Iranian Revolutionary Guard bases in northwest Iran this year, causing a number of casualties, according to medical sources in Tehran. Javadi had arrived in Cyprus last month to meet his mother and sister, who traveled from Iran for a reunion with him after eight years of separation. The women were walking with Javadi and Rashidzadeh on a back street in the restaurant district of Larnaca, a seaport city, when the attackers fired and then fled. A leading investigative theory, according to Western experts, is that Iranian intelligence officials approved and monitored the departure of Javadi's relatives and sent an assassination squad to Cyprus. Swedish authorities warned Cypriot police shortly before the killing that Javadi was under threat and should be protected, but the warning came too late, according to police here. In a statement issued from Stockholm, Komala blamed Tehran's revolutionary leaders for the assassination. Iran has not commented on the allegation. Javadi's death followed the June 4 assassination in Dubai, United Arab Emirates, of Ataellah Bayahmadi, the chief covert intelligence operative of the Paris-based Flag of Freedom organization, and the July 13 slaying in Vienna of Kurdish leader Abdolrahman Qassemlou. Bayahmadi, who in 1979 joined an unsuccessful coup attempt against the revolutionary regime in Tehran, was shot after he arrived in Dubai for a clandestine meeting with dissident Iranian military officers. Western officials believe the meeting was a trap. Qassemlou, whose Kurdish guerrilla movement staged attacks on Iran from Iraqi sanctuaries, was shot as he met secretly with Iranian government agents to discuss his terms for ending his rebellion against Iranian government forces in northwestern Iran. These killings -- each apparently involving careful planning, specialized weapons and intelligence techniques -- have prompted some Western experts to speculate that the death June 3 of Iran's spiritual leader, Ayatollah Ruhollah Khomeini, unleashed an aggressive program of foreign assassinations as a means of keeping foreign-based opposition groups off balance and preventing their interference with the delicate transition from Khomeini's rule. "If it was just the Dubai killing, then you could say there might be a loose cannon or unauthorized operation," one Western specialist on Iran said. "But the Qassemlou operation was carefully planned, and now the Cyprus operation suggests approval at a high level. And they were probably done by the {Mohammed} Reyshahri organization." Reyshahri is Iran's outgoing intelligence minister, responsible for directing foreign intelligence operations and counterintelligence operations that this year have led to arrests of Iranian military officials and diplomats accused of spying for the West. In a cabinet reshuffle recently completed by President Ali Akbar Hashemi Rafsanjani, Reyshahri was reappointed prosecutor general, an indication that he still enjoys the confidence of Rafsanjani and Iran's new spiritual leader, Ayatollah Ali Khamenei.
