NATO hasn't responded immediately to a request for comment on how alliance operations or Turkey's status might be affected after the military said it seized control of the country.

Nothing in NATO's founding 1949 Washington Treaty says anything about intervening in the internal or political affairs of an alliance member, and Turkey kept its NATO membership following past military coups.

The treaty's key clause, Article 5, stipulates that NATO member states agree that "an armed attack against one or more of them in Europe or North America shall be considered an attack against them all," but that language has taken to apply to an external enemy.
