An attack on a luxury hotel in Nairobi killed 14 civilians Tuesday, including one American, before security forces subdued the gunmen.
Kenyan authorities declared that the violence had ended multiple times, only to be contradicted by bursts of gunfire that kept police busy for several more hours. Al-Shabab, the Islamic extremist group based in Somalia, claimed responsibility for the attack, carried out by at least four armed men.
