Iran-backed Shiite Houthi rebels and their allies in Yemen randomly shelled a town Sunday outside of Aden after losing control of some the port city's neighborhoods, killing at least 45 people and wounding 120, officials said. A leader with the Shiite rebels denied shelling Dar Saad, a town just north of Aden and long home to fighters resisting their advances. But Yemeni medical officials and a doctor with an international aid organization said the shelling clearly came from the north and east of Dar Saad, areas under rebel control.
