Nato foreign ministers have agreed to suspend all practical civilian and military co-operation with Russia, following the "illegal" recent annexation of Ukraine's Crimea region.
Speaking to the media, Nato Secretary General Anders Fogh Rasmussen said the move was "a flagrant breach of Russia's international commitments".
"In the light of this, there can be no business as usual," he added.
