A crash that killed 32 tourists from North Korea's chief ally brought "bitter sorrow" to the heart of leader Kim Jong Un, according to Pyongyang's official KCNA news agency. The agency—in a rare admission of bad news—said the Chinese tourists and four North Koreans were killed when a tour bus plunged off a bridge in North Hwanghae province, south of the capital, the BBC reports. Kim "couldn't control his grief at the thought of the bereaved families who lost their blood relatives," KCNA said. The AP reports that China, source of the vast majority of foreign tourists to North Korea, has sent diplomats and a medical team to assist. (More North Korea stories.)
