It advised all U.S. citizens in Guyana to make alternate travel arrangements through Wednesday if they were planning on traveling home on flights with Caribbean Airlines.
The airline’s representative for Guyana, Carl Stuart, said the company has elevated “our level of security involving the police, the military and other agencies.”
“We have been on this since Friday,” he told The Associated Press. “We are on top of this and flights will continue as normal, but we are taking no chances.”
In 2007, a former member of Guyana’s parliament and a naturalized U.S. citizen from Guyana were among four people convicted of participating in a failed plot by a small group of militant Muslims to firebomb John F. Kennedy International Airport in New York.
