BOGOTA, Colombia 

Venezuelan Defense Minister Vladimir Padrino said Thursday that five fighter jets were detected near the country's coast, which he described as a "threat" and "provocation" by the United States.

"They are fighter jets. Imperialism has dared to approach the Venezuelan coast," Padrino said from an air base in a state television broadcast, adding that the presence of the planes was reported by an international airline to a control tower.

"The presence of these planes flying near our nearby Caribbean Sea is rude, a provocation, (and) a threat to the security of the nation," he stated.

Padrino assured that if the US "attacked" the South American nation, the country would launch a "national mobilization."

"I denounce before the world the military harassment, the military threat of the United States Government against the people of Venezuela (...); I denounce before the world this situation, which, I repeat, is nothing more than a provocation, but also a threat to our national security," Padrino declared.

This incident is the latest development in escalating tensions between the two countries. The US deployed 10 F-35 aircraft to Puerto Rico nearly a month ago as part of a military buildup that also includes eight warships. President Nicolas Maduro has previously called this mobilization a "siege" and a "threat."

In recent weeks, four suspected drug traffickers' boats have already been destroyed by US strikes. Venezuela has said it believes that President Donald Trump is using drug trafficking as a false pretext to overthrow Maduro and seize the country's vast oil reserves.

In response to what he views as a military threat, Maduro has mobilized militias, warships, helicopters, and fighter aircraft with 2,500 troops.

The president has also said he is preparing a decree to declare a "state of external unrest," an exceptional measure that would expand his powers.
