MADRID, Nov 22 (Reuters) - Three international airlines

cancelled their flights departing from Venezuela on Saturday

after the U.S. Federal Aviation Administration warned major

airlines on Friday of a "potentially hazardous situation" when

flying over the country.

Brazil's Gol, Colombia's Avianca and TAP Air Portugal

cancelled their flights departing from Caracas on Saturday,

Flightradar24 and Maiquetia International Airport's official

website show.

Aeronautica Civil de Colombia said in a statement there were

"potential risks" of flying in the Maiquetia area "due to the

deterioration of security conditions and increased military

activity in the region."

Spain's Iberia also said they were cancelling their flights

to Caracas from Monday until further notice. The Spanish

company's flight scheduled on Saturday to Madrid from

Venezuela's capital departed.

"The company will assess the situation to decide when to

resume flights to that country," an Iberia spokesperson told

Reuters.

Copa Airlines and Wingo kept their flights departing from

Maiquetia on Saturday.

The U.S. FAA notice cited the "worsening security situation

and heightened military activity in or around Venezuela" and

said threats could pose risks for aircraft at all altitudes.

There has been a massive American military buildup in the

region in recent months, including the U.S. Navy's largest

aircraft carrier, at least eight other warships, and F-35

aircraft.

Latam Airlines flight to Bogota scheduled for

Sunday has also been cancelled, Flightradar24 says.
