A federal judge in Alexandria yesterday sentenced a Washington man to two concurrent two-year prison terms following his conviction on charges of purchasing guns in Virginia under a ficitious name.

Ali Abdul-barr, 30, also known as Morris Haywood Smith, of the 1700 block of 10th St. NW was sentenced by U.S. District Court Judge Albert V. Bryan Jr. to two years on each of two counts of making a false or fictitious statement to a licensed gun dealer in the acquistion of a firearm and/or ammunition.

Abdul-barr, according to federal prosecutors, was a member of a group of black American Muslims who embraced the Islamic beliefs of Ayatollah Ruhollah Khomeini. Another member of the group, Musa Abdul Majid, has been described in court as "a very close friend" of Daoud Salahuddin, accused assassin of exiled Iranian leader Aki Akbar Tabatabai. Majid failed to show up in court earlier this month for sentencing on three convictions for fraudulent weapons purchases. He, like Salahuddin, is believed to have fled the country.

Abdul-barr was convicted of violations of the Firearms Act on Dec. 8 following a jury trial in Alexandria federal court. Judge Bryan continued Abdul-barr's release on a $5,000 bond pending appeal of his conviction.
