WASHINGTON - The CIA is hunting a 9/11 plotter in Pakistan who was a roommate of one of the lead hijackers who struck the twin towers with hijacked jets, the Daily News has learned.

Pakistani military officers yesterday displayed a cache of newly-captured weapons and documents including the German passport of Said Bahaji.

Bahaji, 34, lived with 9/11 plot leaders Mohamed Atta and Ramzi Binalshibh and was part of their Hamburg, Germany, cell, helping to plan the 9/11 attacks.

Ziad Jarrah, the hijacker of the United Airlines jet that crashed in Pennsylvania, attended Bahaji's wedding.

Bahaji is believed to be alive and has rank in Al Qaeda as "a senior propagandist," a U.S. counterterror official told The News.

He also is involved in operational activity.

The passport - which CNN video showed with a Pakistani entry stamp of Sept. 4, 2001 - is evidence the CIA's hunt for Bahaji may intensify.

It was shown to reporters in South Waziristan, the tribal agency where the CIA has launched dozens of missile strikes at Al Qaeda safe houses in the past year.

Operatives typically fork over their passports to the group when they enter the tribal areas.

"Atta and Binalshibh used Bahaji's computer for Internet research," the 9/11 commission's 2004 report said.

"Diskettes seized from Bahaji's residence also contained bomb-making instructions."
