The US Embassy said Tuesday it has been alerted to a possible terrorist threat targeting this month's world cross-country championships in Kenya. The embassy said the threat came from "alleged extremist elements" and that the meet "may be the target of an unspecified terrorist attack." Last month, the US Embassy issued another strong warning to Americans considering a visit to Kenya, saying violent crime was increasing and that Kenyan authorities have limited capacity to prevent it. "The US Embassy is also aware of public statements by leaders of Kenya's Coastal Muslim community threatening to disrupt, through unspecified means, the World Cross Country Championship if the government of Kenya does not satisfy various demands," Tuesday's statement said. No further details were released, and embassy spokeswoman Jennifer Barnes said she had no further comment.
