A police official in Nairobi says police shot dead a couple suspected to be terrorists after they threw four grenades, wounding five officers. Augustine Nthumbi, the officer in charge of the Githurai Kimbo area on the city's outskirts, said Sunday investigators raided the flat where the couple were staying following a tip and ordered them out of their house. Nthumbi says the couple refused to surrender, threw grenades and used their eight-month-old baby as a human shield. Nthumbi say two grenades were recovered from the house, according to a report of the Associated Press.
