Russia claims FBI 'missed' Boston warning

The Boston Marathon bombings could have been prevented if US officials had followed through on Russian intelligence, a senior Moscow official has said.

Valentina Matvienko, the speaker of Russia’s senate, said: “The Russian side warned the American side about the Tsarnaev brothers, but this information was not taken seriously by the American side, which is what led to that tragedy,” the Interfax news agency reported.
