 Horrific bombing at Ukraine's largest children's hospital in the capital of Kyiv. Here's ABC chief foreign correspondent Ian Pannell. Rescuers and dozens of volunteers, including medics, wearing scrubs and lab coats, forming a human chain, combing frantically through the rubble for survivors as children undergoing life-saving treatments were forced to sit on the sidewalk, IVs still in their arms. We visited this hospital many times. It gives critical care to kids with cancer, disease, as well as war wounds.
