Police arrested an American man in northern Kenya who was trying to enter an area of Somalia controlled by Islamist militants. Although the man claimed to be a Muslim, they thought his willingness to travel among the radical al Shabab group was suspicious. He denied any connection to Islamic groups, but the US believes al Shabab is a proxy for al-Qaeda. The Kenyans and Somalians are jumpy and conflicted neighbours. Al Shabab has accused Kenya of training pro-Somali government militants to fight it and its allies in the southern port town of Kismayo, and claim the Kenyans operate three training camps close to the Somali border.
