Kenya's air force bombed two militant camps over the border in neighboring Somalia today. It was the first military response to an attack carried out last week by the Islamist group al-Shabaab. The extremists killed at least 148 students and staff on a university campus. Al-Shabaab promises further attacks until Kenya's cities run, quote, "red with blood." NPR's Gregory Warner in Nairobi reports that Kenyans are worried the real enemy isn't in Somali, but closer to home.
