NBC news reports that US officials were warned not once but twice about a US businessman who was planning to launch terrorist attacks against targets in Mumbai. But unlike the first warning, the second was never passed on to the FBI.
The second warning, which came from David Coleman Headley's second wife, came less than a year before the Mumbai attacks of November, 2008. Those attacks involved a series of coordinated bombings of at least 10 locations over three days and resulted in 166 deaths injuries in India's largest city. The first warning came two years earlier, from Headley's ex-wife.
