The ongoing standoff between the United States and Russia over Ukraine, and the one year anniversary of the Boston Marathon bombing are set to lead the Sunday shows on Easter morning.

Ukraine has instituted an Easter truce but it has become increasingly clear that an agreement inked in Geneva this week is failing to solve the unrest in the eastern part of the country. Pro-Russian militants who have seized control over government buildings are not backing down.

Arseniy Yatsenyuk, Ukraine's prime minister, will present his side of the story on NBC's "Meet the Press" shortly after Russia's ambassador to the United States, Sergey Kislyak gives Putin's point of view on "Fox News Sunday."
