Jordan's Appeals Court reduced harsh sentences handed down on four al-Qaida-linked militants convicted of a foiled terror plot to attack Americans and Israelis during millennium celebrations in the kingdom, according to a ruling announced Tuesday. The court commuted death sentences issued by a military court in September 2000 against the plot's mastermind, Khader Abu-Hosher, and his coconspirator Osama Samar. They will instead serve 20 years in prison with hard labor. Two other cell members, Khalid al-Mughames and Sa'ed Hijazi, will also serve 20- year prison sentences with hard labor instead of life sentences, according to the ruling, which was delivered three weeks ago but only released to the press on Tuesday. The court said its decision was final.
