They’re targeting non-Muslims for slaughter. The Somali terrorist group al-Shabaab has claimed responsibility for the mass execution of Christians in an attack in northern Kenya early today. Witnesses in the village of Kormey said Christian quarry workers were killed, while their Muslim coworkers were set free. Hours after the attack, the interior minister was fired, and the national police chief has resigned. The attack is the latest in a spate of violence stemming from 2011, when Kenyan troops began battling the al-Qaida-linked Islamists in Somalia.
