The government of Qatar says an Egyptian suicide bomber carried out Saturday's attack on a theater popular with Westerners in the capital.
The Qatari Interior Ministry identified the attacker as Egyptian national Omar Ahmed Abdullah, adding that he owned the car used in the bombing. Egypt has not commented on the claim.
The blast, which killed one person and wounded at least 12 others, occurred Saturday evening in Doha during a theater performance near a British school. The British Foreign Office identified the dead victim as a Briton.
The blast came on the second anniversary of the start of the U.S.-led invasion of Iraq, which was strongly supported by the British and Qatari governments.
Oil-rich Qatar - a close U.S. ally - is home to the U.S. military's Central Command operations center for the Middle East.
