Security forces aided by the FBI are trying to prevent rumored “dirty bomb” or car bomb attacks in Mombasa and Nairobi as well as disrupt a Shabaab plot said to involve Ugandan tanker trucks. Police in Mombasa were given shoot-to-kill orders. After the deadly attack on a Likoni church on March 23, the Interior Ministry ordered all urban-dwelling Somali refugees to move to the Dadaab or Kakuma camps; the order affects hundreds of thousands of refugees. A Muslim leader claimed that police had been warned about the Likoni attack but failed to take action.
