BERLIN (Reuters) - Germany summoned the Iranian ambassador to its foreign ministry on Monday to protest that two German journalists held in Iran were not allowed to meet their families over Christmas as promised. Later on Monday, a spokesman for the ministry said that the Iranian foreign minister was arranging a meeting with between the two journalists and their families. Today Foreign Minister Westerwelle spoke several times with his Iranian counterpart, who thereupon met with the members of the families and agreed to a swift meeting in Tabriz. The two families are now on their way to Tabriz, he said. The families had travelled to Tehran after Iran repeatedly promised to allow the visit and the German ambassador stayed in the country over the holidays to arrange the meeting. As such a meeting has so far not been held, the Iranian ambassador was summoned to the foreign ministry this morning... the displeasure of the German government was clearly expressed, Foreign Ministry spokesman Stefan Bredohl told reporters at a regular news briefing. The two reporters for German weekly Bild am Sonntag were arrested in October while interviewing the son of Sakineh Mohammadi Ashtiani, a woman sentenced to death by stoning for adultery. The case has sparked global outrage and highlighted concerns about Irans human rights record. Iran says the reporters did not have necessary permission to work as journalists in the country. An Iranian government spokesman said in early December it was considering Berlins request to free the reporters, whose arrests have added another irritant to Irans relations with the European Union at a time of tensions over its nuclear programme, which the West fears may be aimed at making an atomic bomb.
