New York - A Saudi student who briefly shared a room with Zacarias Moussaoui in Oklahoma pleaded guilty yesterday to making false statements, including lying to the FBI about their plans to visit New York in August. Hussein al-Attas, 24, entered the plea to seven charges in U.S. District Court as part of a deal that keeps him in the country to testify, if needed, against Moussaoui, the only person charged with conspiring to help the 19 Sept. 11 hijackers. Under the plea agreement, al-Attas faces up to six months in prison.
