BRUSSELS (AP) — Members of the U.S.-led alliance must stand shoulder to shoulder to confront simultaneous security threats from Russia and the so-called Islamic State extremist organization, NATO secretary general Anders Fogh Rasmussen said Monday.

In a farewell speech as NATO’s top civilian official, Rasmussen said the alliance finds itself on the front lines of a geopolitical division between “tolerance and fanaticism,” and “democracy and totalitarianism.”
