Shooting has erupted again at military posts across Guinea's capital as the country's presidential guard barricades the streets and blocks access to the downtown area that houses the military's headquarters. The new round of shooting comes after one day of relative calm in which a mutiny by young soldiers against their higher-ups appeared to be giving way in the face of government concessions. An AP reporter heard shots fired from within a number of military camps and checkpoints Thursday, and saw the president's red-beret-wearing troops stopping traffic throughout the city in an apparent attempt to clamp down on the mutineers.
