WARNING: US protests

In an ironic turn of events, three countries have warned their citizens to be on guard when visiting American cities rocked by violent protests after a string of police shootings of black Americans.

The United States regularly issues travel warnings urging Americans to either avoid or exercise caution in countries marred by violence or political instability.

The Bahamas, United Arab Emirates and Bahrain have told their mense to be careful, as protesters marched in US cities throughout the weekend after police killed several black men in Louisiana and Minnesota.

America was also tense after a lone black gunman on Thursday shot dead five police officers during a protest in Dallas.

The US embassy of Bahrain, in the Middle East, on Saturday urged citizens via Twitter to “be cautious of protests or crowded areas occurring around the US.”

Bahamas, a Caribbean nation of mostly blacks, on Friday warned its people to be careful when visiting US cities rocked by “shootings of young black males by police officers”.

“Do not be confrontational and cooperate,” Bahamas foreign ministry said in a travel advisory.

The United Arab Emirates also issued similar warnings.

In July alone, the United States has issued travel warnings for Bangladesh, Venezuela, Iraq and Mali.

It also issued a terror warning for South Africa just before the month of Ramadaan commenced, urging Americans to stay away from larney malls and tourist hotspots.
