Washington - The United States acknowledged Monday that a US military aircraft may have inadvertently wandered into Venezuelan airspace during an anti-narcotics mission.

The US State Department said that the aircraft was operating out of Curacao when the incident occurred on Saturday, and the pilot quickly informed Venezuelan authorities of the navigational mistake.

"He contacted a Venezuelan tower to report the error, stating that he would immediately return to international airspace," the department said. "The exchange was polite and professional."

Venezuelan Foreign Minister Nicolas Maduro said Monday that his government would summon the US ambassador in Caracas, Patrick Duddy, but the State Department said no such summon has been received by the embassy. (dpa)
