U.S. security concerns in the Horn of Africa, particularly at Ras Kamboni, heightened after the September 11, 2001 attacks on the United States. On December 16, 2001, Paul Wolfowitz said the U.S. was meeting with various Somali and Ethiopian contacts to "observe, survey possible escape routes, possible sanctuaries" for Al Qaeda operatives. On March 2, 2002 a briefing was held in the Pentagon discussing the possible use of Ras Kamboni by terrorist groups, including al-Ittihaad al-Islamiya (AIAI) and Al Qaeda. In December 2002, the U.S. established the Combined Joint Task Force - Horn of Africa (CJTF-HOA) to monitor developments in the region and to train local militaries in counterterrorism. When Ethiopian troops entered the Somalian conflict in December 2006, a small number of U.S. special forces accompanied them to give military advice and to track suspected al-Qaida fighters.
