US prosecutors want another chance to seek a stiffer prison term for an Algerian man convicted of plotting to bomb Los Angeles International Airport at the turn of the millennium. In a Friday filing, interim US Attorney Jeffrey Sullivan asked the 9th US Circuit Court of Appeals to review the case of Ahmed Ressam, whose 22-year prison sentence was thrown out in January. Ressam was arrested near the US-Canadian border in December 1999 after customs agents found 124 pounds (56 kilograms) of explosives in the trunk of his car as he disembarked from a ferry at Port Angeles, Washington. Prosecutors said he was intent on bombing the Los Angeles airport on the eve of the millennium. The arrest raised fears of terrorism attacks and prompted the cancellation of New Year's celebrations at Seattle's Space Needle.
