A grenade set off by a gun-man in a Nairobi church killed one person on Sunday and injured at least 10 others, police and witnesses in the Kenyan capital said. The attack targeted the God's House of Miracle Church in Nairobi's Ngara neighbourhood, where residents said they tried in vain to detain the alleged assailant amid the chaos that followed the explosion.
