Two Chechen brothers from Dagestan, members of a Wahhabi cell funded by Saudi al Qaeda, were identified as the terrorists who detonated two bombs at the Boston Marathon last Monday and carried out a bombing-shooting spree at the MIT campus in Waterton outside Boston, Friday, April 19, in which a police officer was killed. Tamerlan Tsarnaev, 26, and Dzhohav Tsarnaev, 19, escaped the MIT campus in a hijacked SUV, chased by the police.
