 Overseas, Russian missiles struck a children's hospital in the Ukrainian capital of Kyiv this morning, killing at least seven people. Videos from the scene show volunteers working with police to sift through the rubble as smoke billowed from the hospital, which treats some of Ukraine's sickest children. The barrage was part of a larger attack which targeted five Ukrainian cities during rush hour. It comes on the eve of a three-day NATO summit in Washington, D.C.
