U.S. Embassy officials in Ankara say two U.S. warplanes accidentally violated Turkish airspace last week near the Iraq border.
U.S. and Turkish officials said they are investigating the incident. The Turkish military said on its Web site that two F-16s briefly crossed into Turkish airspace on May 24. Officials said the incursion lasted about four minutes.
The incursion happened in an area of southeast Turkey near where thousands of Turkish troops are reported to be gathering.
The airspace violation comes as speculation grows over whether Turkish troops will launch a cross-border operation against Kurdish militants in Iraq. Last week, Turkish Foreign Minister Abdullah Gul said no plans were underway for such a raid.
