Dude, if you only depend on the western news agency for your news you'd think this as they seem to regard Africans as being barely human. Point in case, when they reported that two NGO workers (Spanish nurses) had been kidnapped, it was actually four NGO workers that had been kidnapped but the two others were Kenyan so western press only reported that "two people" had been kidnapped. In addition, a Kenyan was also killed in that incident. You can see the details
here. In addition to the above, there were also two policemen who were kidnapped a few months before that and there have been dozens of incursions and killings of Kenyans by Al-Shabab over the last couple of years.
FYI, as much as people like you want it to happen there really is no "chaos" in Nairobi or attacks against Somalis because of this operation. It only exists in the feverish imagination of western journalists.
