Travelers, beware: Tensions in the United States over police shootings of black men and women may pose a threat to your safety.

That is the warning that at least three foreign governments have issued to their citizens in the days since the shooting deaths of Alton Sterling in Louisiana, Philando Castile in Minnesota and five police officers in Dallas.

The advice from the government of the majority-black Bahamas was particularly blunt: Take care in cities where tensions are high.

“We wish to advise all Bahamians traveling to the U.S. but especially to the affected cities to exercise appropriate caution generally,” the Ministry of Foreign Affairs and Immigration wrote in a statement on Friday. “In particular young males are asked to exercise extreme caution in affected cities in their interactions with the police. Do not be confrontational and cooperate.”
