The US Federal Aviation Administration has issued an order prohibiting US carriers from flying below 26,000 feet (approx. 8000 metres) over Venezuelan airspace, citing "increasing political instability and tensions" and "inadvertent risk to flight operations".
"All flight operations in the territory and airspace of Venezuela at altitudes below FL 260 by the persons described in paragraph A below are prohibited until further advised due to increasing political instability and tensions in Venezuela and the associated inadvertent risk to flight operations," the statement said.
According to the statement, the warning applies to all air carriers registered in the United States.
Political crisis in Vaenezuela took another turn on Tuesday morning, when Venezuelan opposition leader Juan Guaido and his supporters gathered in Caracas on a highway in front of La Carlota military base.
