Christmas Day bomber co-operating with investigators

The Nigerian accused of the Christmas Day airline bomb attack has been co-operating with investigators and providing fresh intelligence in multiple terrorism investigations, senior US sources said.

Umar Farouk Abdulmutallab's help could prove to be a national security victory and a political vindication for President Barack Obama, who has been under fire from politicians who say the administration botched the case by giving Abdulmutallab the right to remain silent rather than interrogating him as a military prisoner.
