A car being escorted to a Nairobi police station blew up last night, killing two of the car’s occupants along with two policemen. Security forces said the car could have been targeting a Cabinet Secretary and the Police Inspector General. One of the car’s occupants had explosives on his body. Explosives were also found in another car impounded today in Nairobi. A witness in the trial of Westgate Mall attackers Mohamed Abdi Noor, Liban Omar, Adan Mohamed, and Hussein Mustafah said Noor’s phone number was active in Kenya and Uganda starting in June 2013, three months before the attack.
