At least one person was killed and 21 others injured when an explosion rocked a residential area in northern China’s Shanxi province, creating clouds of smoke and shattering glass in nearby buildings, the state media reported on April 30. The blast occurred at around 1.15pm in Shanxi’s Taiyuan city, state broadcaster CCTV said, adding that the cause was being investigated. Two people remain missing, according to CCTV. Footage circulating on Chinese social media site Weibo – unverified by Reuters – appeared to show several vehicles engulfed in flames outside a building, with dense smoke pouring from the cars and some residential windows. A total of 210 firefighters and 43 fire trucks were deployed to the scene, CCTV said.
