TORONTO – Following the mass shootings in Orlando and Dallas, three countries – U.A.E., Bahrain and The Bahamas – have issued travel warnings about travel to the United States.

U.A.E. was the first to caution its citizens to avoid wearing traditional dress in the U.S. after a man from the United Arab Emirates was falsely accused of being a terrorist while seeking medical treatment.

The Bahrain Embassy in Washington then tweeted to be cautious of protests and crowded areas in the U.S.

Please be cautious of protests or crowded areas occurring around the US. Emergencies call the embassy at 202.342.1111 ext9 or 202.297.0537

The Bahamas on Friday issued a rare travel advisory for any of its citizens visiting the United States, recommending that young men in particular take care in cities affected by recent tensions over police shootings.

A statement from the Ministry of Foreign Affairs warns visitors to “exercise appropriate caution” in light of recent episodes involving police officers and black men. It also advises people not to get involved in demonstrations and to avoid crowds.

“In particular young males are asked to exercise extreme caution in affected cities in their interactions with the police. Do not be confrontational and co-operate,” the statement said.

The U.S. Department of State currently has 42 live travel alerts and warnings for destinations around the world, including Europe, Turkey and Mexico, but none of the countries mentioned above.

There are many suggestions on social media that countries could be retaliating against the U.S. for all the travel warnings they issue, while facing domestic safety issues themselves.
