BRUSSELS, MARCH 29 -- The leader of Moslems in Belgium, the Netherlands and Luxembourg and his aide were shot and killed today, five weeks after the imam distanced himself from Iran's death sentence for author Salman Rushdie. Imam Abdullah Ahdal, 36, a Saudi Arabian and moderate Moslem, and Salem Behir, 40, a Tunisian who headed the Brussels mosque's social services and library, were shot at close range in the imam's office in the mosque, police said. No one immediately claimed responsibility, and no arrests were made. Police said there were no witnesses and no one heard the gunshots. The two men each were shot twice, once in the head and once in the neck, police said. Unconfirmed reports said three hooded men were seen jumping from a van, entering the mosque and then coming out again. The bodies were found by members of the Islamic community this evening. On Feb. 14, Iranian revolutionary patriarch Ayatollah Ruhollah Khomeini issued a death sentence for Rushdie for "The Satanic Verses," a novel many Moslems consider blasphemous. In a Feb. 20 interview on RTBF, Belgium's French-language television network, Ahdal agreed that Rushdie's book was blasphemous. But he said of Khomeini's death sentence: "One should not have done that. Rushdie should have first appeared {before an Islamic tribunal}. He should have explained himself, defended himself. He should have been asked to repent." In democratic societies "everyone has the right to speak his thoughts, to express himself as he wants," Ahdal said. Claude van Engeland, an RTBF reporter, said today that the network had received angry phone calls after the interview from callers who claimed Ahdal, who spoke in Arabic, was improperly translated. Ahdal's mosque, in a park near the European Community headquarters, is part of the London-based World Islamic League. After the killings, police cordoned off the building. At one point a woman wearing a black veil emerged from the building and threatened a reporter with a handgun. Several police officers struggled with the woman and wrested the gun from her. They said later she was Ahdal's widow, outraged by the killing, and that the gun she carried was not that used against the men. Rushdie, a Briton who was born in India to a Moslem family, no longer practices religion. He is in hiding in Britain. Moslems object to "The Satanic Verses" because of a brothel scene in which prostitutes take the names of the Prophet Mohammed's wives and because it suggests Mohammed wrote the holy Koran instead of receiving it from Allah. Members of the Islamic community told reporters outside the building that their mosque takes a very conciliatory tone. "We respect everybody," one said on condition of anonymity. "We do not take radical positions." Mohammed Sulim, a professor of Islamic religion, asked the Moslem community to remain calm. He said, "We are a few days from the Ramadan," which Moslems mark with a month of fasting during the day. "These are days for prayer. One must not seek revenge."
