In the Afghanistan capital Kabul, gunmen disguised as police stormed a maternity hospital. They killed sixteen people, including two newborn babies, mothers and nurses. Gunbattles raged for hours as the security forces struggled to evacuate over one hundred women and their infants. The violence is threatening to further undermine the peace process that started in February between Washington and the Taliban. A warning to our viewers: some of the images in this report are distressing.
