BOGOTA, Colombia (AP) — Three Americans, two Spaniards and a Czech citizen were arrested Saturday after Venezuelan officials accused them of coming to the South American country to assassinate President Nicolas Maduro.

The arrest of the American citizens included a member of the Navy, who Cabello identified as Wilbert Joseph Castañeda Gomez. Cabello said that Gomez was a navy seal who had served in Afghanistan, Iraq and Colombia. Spain's embassy in Venezuela did not reply to a request for comment on the arrests of its citizens.

The U.S. State Department late Saturday confirmed the detention of a U.S. military member and said it was aware of “unconfirmed reports of two additional U.S. citizens detained in Venezuela.”
