The United States Department of State has issued a warning to all Americans who are traveling abroad — be cautious.
The warning comes due to rising tensions in many parts of the world as well as anti-American sentiment.
The heightened sense of security is unusual because warnings typically are given for specific areas or regions and not worldwide.
There are currently wars in Ukraine and Gaza as well as terrorist attacks in the Middle East and protests on college campuses in the U.S. In addition, Haiti and other countries are facing instability.
