German security authorities have issued a warning to the Jewish community of an increased threat of terrorist attack emanating from Lebanon, a senior Jewish official said Sunday. Stefan Kramer, general secretary of the Central Council of German Jews, told Deutsche Presse-Agentur (DPA) the warning had been received more than a week ago, on January 11. He confirmed weekend news reports that increased precautions were being taken. The increased threat was to synagogues and Jewish schools across the country, and not just in Berlin, as was reported earlier, Kramer said. Kramer referred to information from Lebanon and a possible link to the current trial in Dusseldorf of a Lebanese man, Youssefal-Hajj Dib, 23, on charges of attempting to blow up German trains with suitcase bombs in July 2006.
