A letter bomb sent to a Rome tax collection office was intercepted on Thursday, a week after a first bomb exploded, nearly blinding the director who opened it, Italian media reported. "Bomb disposal experts were called in after a suspect package was reported at the Equitalia office," a police spokesman said. The experts were still examining the package and had found "dark powder inside," he said. An Italian far-left group claimed responsibility for the letter bomb last week that wounded the tax collection company's director, following a first foiled attack on the head of Deutsche Bank.
