NATO says five foreign troops have been killed in a helicopter crash in southern Afghanistan.
In a statement, NATO said the crash is under investigation, adding that first reports indicate there was "no enemy activity" at the time of the incident, which it said occurred on March 11.
NATO did not disclose the nationality of the soldiers nor the exact location where the incident occurred.
The crash came on the same day that two U.S. troops and five Afghan police and soldiers were killed in a so-called insider attack by a person in an Afghan military uniform in the restive east of the country.
New U.S. Defense Secretary Chuck Hagel left Afghanistan earlier on March 11 after a difficult first trip to Kabul.
His trip was marred by a suicide-bomb attack near where he was holding a meeting, as well as differences with Afghan President Hamid Karzai, who suggested the United States benefited from Taliban attacks, a charge rejected by U.S. officials.
