WASHINGTON, Sept 10 (AFP) - The United States on Friday warned its citizens abroad to be mindful of the threat of terrorism targeting Americans and American interests, particularly Al-Qaeda attacks with chemical and biological agents.
The "Worldwide Caution" said the State Department "is deeply concerned about the continued threat of terrorist attacks against US citizens and interests abroad, as well as the potential for demonstrations and violent actions against US citizens and interests overseas."
"In reaction to the execution of hostages in Iraq, there have been demonstrations and associated violence in the hostages' country of origin," said the warning.
"While Americans are generally not the targets in such incidents, US citizens could be caught up in the violence. US citizens are reminded to maintain a high level of vigilance and to take appropriate steps to increase their security awareness."
The State Department said it "remains concerned by indications that Al-Qaida and affiliated groups continue to prepare to strike US interests abroad, after attacks in Europe, Asia and the Middle East.
"Future Al-Qaida attacks could possibly involve non-conventional weapons such as chemical or biological agents as well as conventional weapons of terror, to include explosive devices.
"Terrorists do not distinguish between official and civilian targets," said the statement.
"These may include facilities where U.S. citizens and other foreigners congregate or visit, including residential areas, business offices, clubs, restaurants, places of worship, schools, hotels and public areas."
said the State Department.
"US citizens are encouraged to maintain a high level of vigilance and to take appropriate steps to increase their security awareness, said the State Department.
