DUBAI (Reuters) - A U.S. B-1 bomber exploded while landing in a Qatari air base due to a technical fault on Friday, Qatar-based Al Jazeera television reported.

The television station did not say if anyone was hurt in the incident at the Al Udeid air base south of the Qatari capital Doha. It said earlier a B-52 plane had exploded.

A U.S. air force spokesman said he had no immediate report of such an incident and would check.

Al Udeid is used by U.S. forces in the Gulf Arab country, which hosted the advance headquarters of the U.S.-led forces in the 2003 invasion of Iraq.
