Washington:
Citizens of 14 nations, including Pakistan, Saudi Arabia and Nigeria, who are flying to the United States will be subjected indefinitely to the intense screening at airports worldwide that was imposed after the Christmas Day bombing plot, Obama administration officials announced Sunday.
But American citizens, and most others who are not flying through those 14 nations on their way to the United States, will no longer automatically face the full range of intensified security imposed after the attempted bombing of a Northwest Airlines flight, officials said.
The change represents an easing of the immediate response to the attempted bombing of a flight from Amsterdam to Detroit. But the action on Sunday further establishes a global security system that treats people differently based on what country they are from, evoking protests from civil rights groups.
Citizens of Cuba, Iran, Sudan and Syria - countries that are considered "state sponsors of terrorism" - as well as those from "countries of interest" - including Afghanistan, Algeria, Lebanon, Libya, Iraq, Nigeria, Pakistan, Saudi Arabia, Somalia and Yemen - will face the special scrutiny, officials said.
Passengers holding passports from those nations, or taking flights that originated or passed through any of them, will be required to undergo full-body pat downs and will face extra scrutiny of their carry-on bags before they can board planes to the United States.
In certain countries that have more advanced screening equipment, travellers also will be required to pass through so-called whole-body scanners that can look beneath clothing for hidden explosives or weapons, or they may be checked with a device that can find tiny traces of explosives.
On Sunday, Prime Minister Gordon Brown of Britain announced that whole-body scanners would be introduced in that country's airports. Officials in Amsterdam announced last week that they would begin using the scanners on passengers bound for the United States.
Many, though not all, other passengers coming to the United States will face similar measures, but that screening will be done randomly or if there is some reason to believe that a particular passenger might present a threat, officials said.
The changes will mean that any citizen of Pakistan or Saudi Arabia will for the first time be patted down automatically before boarding any flight to the United States. Even if that person has lived in a country like Britain for decades, he will be subject to these extra security checks.
In the United States, a requirement for "second screening" has for a number of years already been in effect for a dozen countries, a fact that is not widely known.
Nawar Shora, the legal director at the American-Arab Anti-Discrimination Committee, says the rule wrongly implies that all citizens of certain nations are suspect.
"I understand there needs to be additional security in light of what was attempted on Christmas Day," Shora said, adding that he intended to file a formal protest on Monday. "But this is extreme and very dangerous. All of a sudden people are labelled as being related to terrorism just because of the nation they are from."
Charles Oy, 28, of Chicago is an American who was born in Nigeria. He said that he detected heightened security over the weekend - not in Nigeria but upon his arrival on Sunday at O'Hare International Airport in Chicago. He was one of a few passengers taken aside for an individual interview, and his bags and passport were examined.
The suspect arrested in the Northwest Airlines episode, Umar Farouk Abdulmutallab, 23, was Nigerian, but Oy said that the added scrutiny did not leave him discouraged. "I feel it is very isolated, and is something not characteristic of Nigeria," he said. "I had no particular feelings of unpleasantness. I understand it is part of the world we live in. I factor all that into my travelling. If it happens, I roll with it."
A homeland security official said that the Obama administration did not consider this move a step in the direction of racial profiling, which the Transportation Security Administration has said it has long tried to avoid.
Domestically, passengers travelling in the United States may notice more canine bomb-detection teams or face occasional extra checks of carry-on bags. Additional behavioural detection officials are also in airports to observe passengers for any signs that might offer a hint of a plot. But there have been no comprehensive changes in screening at domestic airports.
David Castelveter, a spokesman for the Air Transport Association, the airlines' trade organization, said the group had been "closely coordinating" the enhanced security measures "with the convenience of customers in mind. I believe we accomplished that," he said Sunday.
