MADINAH, 3 February — The Civil Defense Directorate is investigating the death of a woman and her two children in Hanakiyah, 100 kilometers east of Madinah. The three were drowned in a pool during heavy rains in the region recently. Two Civil Defense officers and three others are being questioned, an official source said. The directorate had earlier set up an inquiry into a fire in which a woman and her four children were killed. The inquiry, however, cleared the Civil Defense of blame in the case.
