More than 15 years after al-Qaida destroyed the U.S. Embassy in Nairobi with a massive truck bomb that killed more than 200 people, fear is rising that U.S. diplomatic personnel and property could again be targeted, with U.S. Ambassador Robert Godec telling a town hall meeting in late May 2014 "We know that there's a threat, and we know it's serious" and armed Marines now being stationed on the embassy’s roof.
