Bombers could have been thwarted, Keating reports

MOSCOW — Russian intelligence officials believe that if US ­authorities had acted on their ­detailed warnings about Tamerlan Tsarnaev wanting to join an Islamic insurgency, the Boston Marathon bombings could have been averted, US Representative William R. ­Keating said Thursday in Moscow after a series of meetings with ­senior members of the Russian ­Federal Security Service.

Keating said the counterintelligence officials had shown him specific information that convinced them Tsarnaev “had plans to join the insurgency back in” Dagestan, a restive region in the North Caucasus mountains on Russia’s southern rim.
