MOSCOW (AP) — Russia's foreign ministry on Saturday promised it would offer strong assistance to Ukraine to overcome its crisis, but emphasized that the ultimate responsibility for reducing tensions lies with Ukrainians rather than outsiders. The comments in a statement came two days after top diplomats from Ukraine, Russia, the United States and the European Union issued a statement calling for an array of actions including the disarming of militant groups and the freeing of public buildings taken over by insurgents. "The Russian side noted that the questions of resolving the internal political crisis should be decided by Ukrainians themselves in close cooperation with a special monitoring mission" of the Organization for Security and Cooperation in Europe, said a statement summarizing the meeting.
