WASHINGTON
(AP) -- Americans should be alert to the possible travel risks,
especially during the holidays, following increased terrorist threats
around the world, the State Department warned on Monday.
A
travel alert, which is to be in effect until Feb. 24, said current
information suggests that militants with the Islamic State, al-Qaida,
Boko Haram and other terrorist groups continue to plan attacks in
multiple regions.
U.S. authorities said the likelihood of terror attacks
will continue as members of IS return from Syria and Iraq, and other
individuals not affiliated with terror groups engage in violence on
their own.
Extremists have targeted sporting
events, theaters, open markets and aviation targets. In the past year,
there have been multiple attacks in France, Nigeria, Denmark, Lebanon,
Turkey and Mali. IS has claimed responsibility for the Oct. 31 bombing
of a Russian airliner in Egypt, killing 224 people.
"U.S.
citizens should exercise vigilance when in public places or using
transportation," the alert said. "Be aware of immediate surroundings and
avoid large crowds or crowded places. Exercise particular caution
during the holiday season and at holiday festivals or events."
The State Department said the U.S. is exchanging information with allies about threats of international terrorism.
The
travel alert was issued the same day that Belgium's prime minister
announced that Brussels would remain at the highest alert level for at
least another week. The increased security measures following the Nov.
13 attacks in Paris that killed 130 people have virtually shut down the
Belgian capital.
