WASHINGTON (AFP) - Two Somalis living in the US have been charged with plotting to support terror groups by travelling to Somalia to train to join the "jihad", court documents showed Tuesday. Abdifatah Yusuf Isse, 25, who was arrested in February, and Salah Osman Ahmed, 26, were charged with "conspiracy to kill, kidnap, maim or injure persons in a foreign country." The indictment alleged they "did provide material support and resources, namely personnel, including themselves, knowing and intending that the material support and resources were to be used in preparation" for an attack. The case before a federal court in Minneapolis dates back to February, and the two are accused of travelling to Somalia between September 2007 and December 2008 "so that they could fight jihad in Somalia". At least 17 Somalis have disappeared in past months, Omar Jamal, director of the Somali Justice Advocacy Centre, told AFP. In October, a 27-year-old American-Somali from Minneapolis became the first US citizen to carry out a suicide attack in Somalia.
