MANAGUA, Nicaragua (AP) - Seven people were killed in flooding in Nicaragua, the Red Cross said Wednesday, raising the death toll to at least 29 from weeks of heavy rains across Central America. The rains sparked flash floods, caused swollen rivers to jump their banks and set off avalanches. The high waters have damaged crops and destroyed highways and bridges throughout Central America, which is still recovering from the billions of dollars of damage caused by Hurricane Mitch last year. The deaths in Nicaragua occurred Tuesday and were the first reported there since the rains began Sept. 8. President Arnoldo Aleman ordered a state of emergency throughout the country.
