A senior United Nations official says the man who bombed the U.N.'s headquarters in Baghdad in 2003 has been sentenced to death.

The chief of the U.N. human rights office in Baghdad, Gianni Magazzeni, Friday announced that an Iraqi court had convicted and sentenced a man who had confessed to the attack.

Speaking to reporters in Geneva, Magazzeni said the man is reported to be a member of al-Qaida in Mosul.

The convicted individual's name was not immediately available.

Twenty-two people, including the U.N. High Commissioner for Human Rights Sergio Vieira de Mello, were killed in the August 2003 bombing of the U.N. compound in Baghdad.

The attack prompted the U.N. to temporarily withdraw its staff from Iraq.
