Photo: Screenshot from video posted by China News ServiceOne person has died and two remain missing after an explosion at a single-story house in Wangqiao community in Yihe New Area, Linyi, East China's Shandong Province, at 3:38 pm on Friday, according to a statement released by the Yihe New Area authority on Friday night.
Following the explosion, local public security, fire and rescue, emergency management, housing and urban-rural development authorities formed a joint working group and immediately rushed to the scene to carry out emergency rescue operations.
As of Friday night, one person had been confirmed dead and two remained missing. Other injured people had been taken to hospital for treatment and none were in life-threatening condition. Search, rescue and cleanup operations at the site were still underway, according to the statement.
A preliminary investigation indicated that the explosion was suspected to have been caused by a tenant surnamed Wang illegally storing explosives used for illegal fishing at the property, the statement said.
Residents of nearby residential buildings have been properly accommodated, while an investigation into the cause of the accident and follow-up handling are proceeding in an orderly manner, according to the statement.

【环球时报-环球网报道 记者 樊巍 通讯员 高诗淇、桑茜】9月13日21时18分,由中国航天科技集团有限公司所属中国运载火箭技术研究院(以下简称“火箭院”)抓总研制的长征七号A运载火箭,在海南文昌航天发射场点火升空,成功将中星1E卫星送入预定轨道,未来,该卫星可为用户提供高质量通信广播电视服务。据了解,长七A火箭是我国新一代中型运载火箭的主力构型,是在长征七号运载火箭和长征三号甲系列运载火箭三子级基础上、通过组合化设计形成的高轨三级液体捆绑式运载火箭,地球同步转移轨道运载能力不低于7吨,填补了我国运载火箭地球同步转移轨道5.5至7吨运载能力的空白,可适配直径4.2米和3.7米两种整流罩,具备一箭一星和一箭双主星发射能力。长七A火箭主任设计师魏远明在接受媒体采访时介绍,执行本次发射任务的长七A遥五火箭,采用4.2米直径整流罩的构型,全箭高度60.1米,与2021年3月12日发射的遥二火箭高度一致。长七A火箭作为我国首型采用助推器与芯一级集束式分离技术的捆绑火箭,相比通常先分离助推器、再分离芯一级的方式,减少了一次分离环节,使火箭捆绑连杆结构更加简化。

B | 同时,集束式分离也减少了一个助推器落区,整个组合体都在一个落区内,更加有利于控制火箭残骸落区。此次任务是长七A火箭第四次执行发射任务,火箭状态正在逐步固化,同时为进入高密度发射阶段提前准备。魏远明介绍,型号队伍针对火箭技术设计进行了多项优化改进,在确保测试覆盖性的前提下,通过优化流程顺序、并行工作、合并测试等方法,将发射技术流程由32天缩减至26天。不仅如此,根据高轨卫星整体发展态势,以及高轨卫星配置大尺寸天线的迫切需求,长七A火箭未来还将研制5.2米整流罩的新构型,进一步提高火箭的任务适应性。
