WASHINGTON -- The Obama administration has more than doubled, to about 21,000 names, its secret list of suspected terrorists who are banned from flying to or within the United States, including about 500 Americans, the Associated Press has learned.
The size of the government's secret no-fly list has jumped from about 10,000 in the past year, according to government figures provided to the AP.
The surge comes as the government says it is close to defeating al-Qaida, after killing many of its senior members. But senior officials said the threat does not stop there.
"As long as we sustain the pressure on it, we judge that core al-Qaida will be of largely symbolic importance to the global jihadist movement," Director of National Intelligence James Clapper told Congress Thursday.
"But regional affiliates and, to a lesser extent, small cells and individuals will drive the global jihad agenda."
Those are the people added to the no-fly list, current and former counterterrorism officials said. Most are from other countries; about 500 are Americans.
"Both U.S. intelligence and law enforcement communities and foreign services continue to identify people who want to cause us harm, particularly in the U.S. and particularly as it relates to aviation," Transportation Security Administrator John Pistole said.
Affiliated terror groups in Yemen, Pakistan, Somalia, Algeria and elsewhere, as well as individuals who ascribe to al-Qaida's beliefs, "All are in the mix," said Michael Leiter, former director of the National Counterterrorism Center. "And no one is claiming that they are shrinking."
The flood of new names began after the failed Christmas 2009 bombing of a Detroit-bound jetliner. The government lowered the standard for putting people on the list, then scoured its files for anyone who qualified.
The government will not disclose who is on its list or why someone might have been placed on it.
