SOUTHERN CHINA (CNN/CCTV) -- A sewer explosion tore through an 80-meter road section in downtown Beihai of south China's Guangxi Zhuang Autonomous Region on Wednesday, resulting in zero casualties.
Cameras installed on nearby residential buildings recorded the entire event. Surveillance footage shows that an explosion originating underground hit at 14:22, blowing off the road surface, sending concrete pieces flying to all directions. Three adults and an infant were in the vicinity when the explosion occurred, according to the video. However, no people were injured.
The explosion damaged several nearby light poles, grass patches and railings.
Upon their arrival to the scene, firefighters cordoned off the area, evacuated residents living nearby and took a sample of the air around the explosion site.
The underground sewer tunnel contains natural gas pipelines and high-voltage cables, which are highly dangerous, according to firefighters.
