WASHINGTON — In a sign of growing concern over Islamic militants' training camps in Pakistan, the Department of Homeland Security has ordered its inspectors at America's largest airports to scrutinize all travelers of Pakistani descent -- including U.S. citizens -- in an effort to catch terrorist trainees who might try to enter the United States, officials said Wednesday.
In its warning, which began circulating June 17, the Customs and Border Protection agency requested intensified searches at checkpoints at Los Angeles International Airport and at the main international airports in New York, Washington, Chicago, Detroit and Newark, N.J.
In particular, agents are being told to look for signs of injuries that could have been received during paramilitary training -- such as rope burns, unusual bruises and scars.
A Pakistani diplomat in Washington decried the warning as unwarranted and said it could undermine relations between the U.S. and Pakistan.
A Homeland Security official, who spoke on condition of anonymity, confirmed that the warning had been issued, but said it was confidential and described it as one of many such briefings given to agents as part of the department's developing border enforcement process. He said it was the first to address training camps in Pakistan.
"We don't have specific intelligence that indicates there is a mass exodus of people from Pakistan training camps intent on coming here to do attacks," he said. "It's more that there are terrorist training camps there, as there are elsewhere around the world, and we want to tell people to be on the lookout."
The official said he could not discuss operational details, including how the agents will try to ascertain whether a passenger is of Pakistani origin. But he said the agents have been instructed to take particular note of recent travelers to Pakistan and "to look for other clues."
Most of the camps in Pakistan are thought to be overseen by militants who belong to fundamentalist Islamic organizations with links to Al Qaeda, the official said. He added that they were probably less sophisticated than the training operations that Al Qaeda oversaw in Afghanistan before the U.S.-led military campaign to destroy them in late 2001.
The warning to customs agents was based on general concerns about activity at such camps, and not on any specific information about a planned attack, the official said.
