Navy investigators say some of the U.S. sailors detained by Iran earlier this year said too much.

Fox's Rachel Sutherland reports from Washington:

A Navy report says some of the ten captured sailors gave interrogators sensitive information like computer and phone passwords. One sailor revealed the top speed of his vessel. Admiral John Richardson says the Navy investigation also concluded Iran violated international law.

(Richardson) They violated sovereign immunity by boarding, searching and seizing the boats and by photographing and videotaping the crew

The report blames a series of missteps by the crew and their superiors for the sailors' capture in the Gulf in January.
