In the coastal resort of Vina del Mar on Sunday, nearly 5,000 protesters battled riot police following the largest ever memorial service at the grave of Allende, who perished in the coup.Reporters said Gen. Pinochet's bodyguards opened fire after his motorcade was stoned in Cerro Navia, a working-class suburb north of Santiago. They said at least four protesters suffered bullet wounds.
