Yemeni police have freed a German national arrested along with seven other foreigners in October for alleged links to the al-Qaeda terrorist network and for attempts to smuggle weapons to Somalia, a police source said on Saturday. The source, who spoke on condition of anonymity, said the man was handed over to two German diplomats late on Thursday. "He was released after investigations by security interrogators established that the man was not involved in the weapons smuggling activities," the source told Deutsche Presse-Agentur dpa. The source would not provide further details, and German embassy officials in Sana'a refused to comment. The man was among a group of eight foreigners arrested in Sana'a on October 16. The other suspects are three Australians, a Briton and a Dane, another unidentified Westerner and a Somali. "Initial investigations suggest that the men belonged to the al- Qaeda organization," an interior ministry statement said last week. Security sources have told dpa that all the seven Westerners are Muslims who have been studying Arabic at private schools in Sana'a.
