A senior military official tells Fox News he's hopeful about the sailors being transferred Wednesday morning.
The official also said that one of the sailors is female.
Pentagon officials said the incident occurred near Farsi Island in the Gulf. They said one of their two small boats had mechanical trouble, causing one or both to run aground. The sailors were then picked up by Iran and taken to the island. But it is unclear where they are now.
The boats were moving between Kuwait and Bahrain at the time, and the Pentagon briefly lost contact with the crews.
A senior Obama administration official told Fox News that Iranian authorities have assured the United States of the sailors' “safety and well-being” and said they “will promptly be allowed to continue their journey.”
The semi-official Iranian news agency, FARS, said the sailors were trespassing in Iranian waters.
