Boston blasts: Obama vows answers after Boston bombing suspect held

 WASHINGTON (AFP) - President Barack Obama vowed to find out what turned two young United States residents accused of the Boston bombings to hate, after the second suspect was captured alive, ending a week of horror.

Mr Obama said in a brief on-camera statement that the attacks had failed because Americans refused to be terrorised and heaped praise on police and law enforcement services while remembering the dead and injured.
