Nevertheless, U.S. citizens are urged to maintain a high
level of vigilance and to take appropriate steps to increase
their security awareness to reduce their vulnerability.
Americans should maintain a low profile, vary routes and
times for all required travel, and treat mail and packages
from unfamiliar sources with suspicion. In addition,
American citizens are also urged to avoid contact with any
suspicious, unfamiliar objects, and to report the presence
of the objects to local authorities. |
