Detained US sailors’ navigational error cited by Defense chief Carter

TAMPA, Fla. (AP) — Defense Secretary Ash Carter said Thursday it appears a navigational error caused the crews of two Navy boats to stray into Iranian waters in the Persian Gulf, where they were detained overnight by Iran and released.
"They obviously had misnavigated … that's how they believe they ended up in this circumstance," Carter said in an interview in Miami with Fusion network. "They did not report this navigational error at the time. It may be that they were trying to sort it out at the time they encountered Iranian boats. … We don't know that fully yet."
