SANAA-- Al-Qaeda claimed the failed December 25 bombing of a US-bound aircraft in a statement posted on an Islamist website on Monday, US monitoring organizations said.

The statement which was accompanied by a picture of suspected would-be bomber Umar Farouk Abdulmutallab boasted that the "Nigerian brother" broke all security barriers for his operation, dispelling the "great myth" of American intelligence, SITE Intelligence said.

He used explosives technology developed by the mujahedeen in Al-Qaeda in the Arabian Peninsula's (AQAP) "manufacturing department," it said.

AQAP acknowledges that a "technical fault" caused the failure in the operation," the statement added.

Another US monitoring group Intelcenter also reported the same posting.
