A vessel was recently attacked off the coast of Nigeria, and the captain and chief engineer -- believed to be U.S. citizens -- were taken off the craft, a U.S. official confirmed Thursday.

The attack happened Wednesday in the Atlantic Ocean's Gulf of Guinea, off the western African nation's coast, UK-based security firm AKE reported.

Further details about the attack weren't immediately available.
