PARIS - The head of NATO says it is responding to Russia's military intervention in Ukraine by suspending most of the military alliance's meetings with Russia and reviewing all of its co-operation with Moscow.

NATO Secretary-General Anders Fogh Rasmussen said Wednesday that ambassadors for NATO's 28 member states decided after a meeting with their Russian counterpart to suspend plans for a joint mission as well as all civilian and military meetings.

Rasmussen said because of Russia's military action in Ukraine's Crimean peninsula "the entire range of NATO-Russia co-operation (is) under review."

Rasmussen said the alliance will continue to meet with Moscow at the political level but insisted that halting all other co-operation "sends a very clear message to Russia."

He also said NATO decided "to intensify our partnership with Ukraine."
