Nov. 25 (UPI) -- Tensions between the United States and Venezuela has prompted many airlines to cancel international flights to the South American nation, which has stranded some travelers.

Several international airlines have canceled flights to the Venezuelan capital of Caracas after the Federal Aviation Administration on Friday cautioned them against flying over Venezuela as the United States increases its military presence and activities to thwart what it says is drug smuggling from Venezuela and other South American nations, Fox News reported.

The FAA cited a "worsening security situation and heightened military activity in and around Venezuela" when issuing its cautionary notice, according to euro news.

The disruption of international air service has left some global travelers stranded in Caracas and prompted the Venezuelan government to demand the airlines resume their services, the BBC reported.
