NATO leaders were to meet Sunday after the interim Ukrainian government requested the alliance's support against Russia, whose parliament authorised the use of military force in the country. "North Atlantic Council will meet tomorrow followed by NATO-Ukraine Commission," NATO's Secretary General Anders Fogh Rasmussen said late Saturday on Twitter. The council consists of the permanent representatives, or NATO ambassadors, of member countries. Ukraine's Foreign Minister Sergei Deshchiritsya asked NATO to look at possible ways to help it protect its territorial integrity, he told reporters.
