According to a February 2010 document published by The Telegraph, three Qatari men are suspected of having been involved in planning the September 11 attacks. All have since evaded arrest.
On September 10, 2001, the three men flew from Los Angeles to London after having spent approximately one month in the United States.
The individuals are suspected of having provided surveillance and other assistance to the hijackers. They spent time at the World Trade Center in New York, the White House in Washington, D.C., and in Los Angeles.
According to the document, while in Los Angeles the three paid for a hotel room in cash, and “during the last few days of their stay, requested that their room not be cleaned.”
“Hotel cleaning staff grew suspicious of the men because they noticed pilot type uniforms, several laptops, and several cardboard boxes addressed to Syria, Jerusalem, Afghanistan, and Jordan in the room,” according to the document.
“The men had a smashed cellular phone in the room and a cellular phone attached by wire to a computer. The room also contained pin feed computer paper print outs with headers listing pilot names, airlines, flight numbers, and flight times.”
One mysterious detail about the group’s activities is that the three men had booked seats on a September 10 flight from Los Angeles to Washington, D.C., but failed to board. The same plane was flown into the Pentagon the next day.
The document also directs that Mohamed Ali Mohamed Al Dahham Al Mansoori be added to the TSA terror watchlist. The document says that Mansoori, who in addition to the three Qataris is suspected of assisting in the September 11 attacks, was not, as of the February 2010 cable, on the watchlist.
The document was sent from the U.S. embassy in Qatar. It was not intended to be declassified until 2020.
