The sailors - nine men and one woman - were reportedly being held at an Iranian Revolutionary Guard Corps base on Farsi Island in the Persian Gulf. Iran had originally told the US that the sailors would be returned "promptly," but ended up detaining them overnight.

The semiofficial Fars news agency in Iran said that members of the hardline IRGC had confiscated GPS equipment from the boats, according to The New York Times. The news agency said the data from the equipment would "prove that the American ships [were] 'snooping' around in Iranian waters."
