Federal officials are warning law enforcement agencies in the United States that
terrorists might strike trains and buses in major U.S. cities in coming months
with explosives hidden in bags or luggage.
A Federal Bureau of Investigation bulletin says al-Qaida and other terrorist
groups have demonstrated the intent and capability of attacking public transportation
systems using a variety of bombs. The bulletin notes last month's train bombings
in Madrid that killed more than 190 people.
Meanwhile, the U.S. government says a program to photograph and fingerprint
foreign visitors will be expanded beginning September 30 to include travelers
from some of America's closest allies.
The Homeland Security Department says the change affects citizens from 27
countries allowed to travel without a visa in the United States for up to 90
days. The list of countries includes Britain, Japan, Australia and New Zealand.
Visitors from other countries already face those procedures, which were implemented
after the September 11 terrorist attacks.
In another bulletin sent to law enforcement agencies on Wednesday, the FBI
said terrorists may attempt to enter the United States using cultural, arts
or sports visas, known as P-Visas. It says recent intelligence indicates that
terrorist groups may want to exploit the State Department's P-Visa program
to place operatives on U.S. soil.
