Americans have been issued with a global travel alert over fears of attacks from terrorists around the world.
The US State Department has warned all citizens to be vigilant citing threats from ISIS, al-Qaeda, Boko Haram and “other terrorist groups”.
They have advised everyone to take caution in public places, during holidays and at large gatherings such as sporting matches or concerts.
The alert expires on 24 February next year, the State Department said.
It comes in the wake of the Paris terror attacks last Friday which claimed the lives of 130 people.

The alert on its website reads:

“Current information suggests that ISIL (aka Da’esh), al-Qa’ida, Boko Haram, and other terrorist groups continue to plan terrorist attacks in multiple regions.  These attacks may employ a wide variety of tactics, using conventional and non-conventional weapons and targeting both official and private interests.  This Travel Alert expires on February 24, 2016.

Authorities believe the likelihood of terror attacks will continue as members of ISIL/Da’esh return from Syria and Iraq.  Additionally, there is a continuing threat from unaffiliated persons planning attacks inspired by major terrorist organizations but conducted on an individual basis.  Extremists have targeted large sporting events, theatres, open markets, and aviation services.  In the past year, there have been multiple attacks in France, Nigeria, Denmark, Turkey, and Mali.  ISIL/Da’esh has claimed responsibility for the bombing of a Russian airliner in Egypt.
U.S. citizens should exercise vigilance when in public places or using transportation.  Be aware of immediate surroundings and avoid large crowds or crowed places.  Exercise particular caution during the holiday season and at holiday festivals or events.  U.S. citizens should monitor media and local information sources and factor updated information into personal travel plans and activities.  Persons with specific safety concerns should contact local law enforcement authorities who are responsible for the safety and security of all visitors to their host country.  U.S. citizens should:

• Follow the instructions of local authorities.  Monitor media and local information sources and factor updated information into personal travel plans and activities.
• Be prepared for additional security screening and unexpected disruptions.
• Stay in touch with your family members and ensure they know how to reach you in the event of an emergency.
• Register in our Smart Traveler Enrollment Program (STEP).

Foreign governments have taken action to guard against terrorist attacks, and some have made official declarations regarding heightened threat conditions.  Authorities continue to conduct raids and disrupt terror plots.  We continue to work closely with our allies on the threat from international terrorism.  Information is routinely shared between the United States and our key partners in order to disrupt terrorist plotting, identify and take action against potential operatives, and strengthen our defenses against potential threats”.
