The Civil Defense asked citizens and expatriates all over the Kingdom to take to all necessary precautions when they go out when it rains. According to local newspapers on Wednesday, the rain and floods have washed away a number of roads, destroyed houses and damaged agriculture in various regions. A number of experts have criticized the apathy of some government departments to ward off imminent threats posed by rainwater. Ihasan Abu Hilaiqa, an economist, said the largest quantity of rain in the Kingdom was not more than 59 mm, which is 0.045 percent of the rains that usually fall in Bangladesh. "Though the amount of rain is too little, our concerned departments and the drainage projects could not contain its effects properly," he said. Abu Hilaiqa asked the National Anti-Corruption Commission (Nazaha) to investigate the failure of the mega drainage projects, which cost millions of riyals, to drain rainwater.
