香港高层火灾造成44人死亡；279人失踪
Summary
香港大埔区发生一起毁灭性火灾，已造成至少44人死亡，279人失踪，成为该市数十年来最致命的火灾。
周三下午，香港大埔区宏福苑住宅区发生大火，导致至少44人死亡，279人失踪。火灾起于一栋32层高楼的外部脚手架，迅速蔓延至该住宅区八栋楼中的七栋，燃烧迅速蔓延，主要因竹制脚手架和建筑网的助燃作用。
消防员在高温和浓烟中奋力扑救，火势持续至周四。消防处将事件升级为最高级别的五级火警，出动了140多辆消防车和60多辆救护车赶赴现场。
遇难者中包括一名37岁的消防员，拥有九年服役经验。警方已逮捕三名年龄在52至68岁之间的建筑公司男子，涉嫌因重大疏忽导致他人死亡。调查显示，火灾迅速蔓延可能与电梯大堂附近安装的易燃材料（包括聚苯乙烯泡沫板）有关。
约900名居民已被疏散至临时避难所。中国国家主席习近平对遇难者家属表示慰问，并敦促全力扑灭火灾，尽量减少进一步的损失。
