Yes, a citizen of our friend and ally Saudi Arabia. Also, note that he was a medical student, not some desperately poor fellow driven to this by his lack of opportunities in life. From AP, with thanks to all who sent this in:
CAIRO, Egypt – The suicide bomber who killed 22 people when he blew himself up in a U.S. mess hall in the northern Iraqi city of Mosul was a Saudi medical student, an Arab newspaper reported Monday.
The Saudi-owned newspaper Asharq Al-Awsat identified him as 20-year-old Ahmed Said Ahmed al-Ghamdi, citing unnamed friends of the man’s father. The friends said members of an Iraqi resistance group contacted al-Ghamdi’s father to tell him his son was the suicide bomber who carried out the Dec. 21 attack, the deadliest on an American installation in Iraq.
The father refused to discuss the suicide bombing, but told the newspaper his son had gone to Iraq to fight the Americans and had died there. The family held a mourning ceremony the paper said. It did not say when the ceremony was held or where in Saudi Arabia the family lived.
