WASHINGTON- Defense Secretary Ash Carter is welcoming the release of 10 U.S. Navy sailors held overnight by Iran. Their boats had crossed into Iranian waters.
    
The nine men and one woman were released by Iran today, along with their vessels, after the head of Iran's Navy says it was determined that the sailors had a problem with their navigation system.
    
Carter is thanking Secretary of State John Kerry for his "diplomatic engagement" on the issue. Kerry has had a close relationship with Iranian Foreign Minister Mohammed Javad Zarif after the recent nuclear deal between the Islamic Republic and world powers.
    
Vice President Joe Biden said that the U.S. did not apologize to Iran for the incident.
