A fire apparently set as part of an escape attempt swept through an Argentine prison cellblock and killed at least 29 inmates, authorities said Monday. The fire broke out late Sunday in one of the cellblock complexes of a maximum security prison for men in the central province of Santiago del Estero, said Ricardo Daives, the province's justice minister. Another 10 people were hospitalized for smoke inhalation and other injuries, Daives told the independent news channel "Todo Noticias".
