Hong Kong fire­fight­ers found dozens more bod­ies Fri­day in an in­ten­sive apart­ment-by-apart­ment search of a high-rise com­plex where a mas­sive fire en­gulfed sev­en build­ings, and au­thor­i­ties ar­rest­ed an­oth­er 8 peo­ple in­volved in the tow­ers’ ren­o­va­tion. The death toll in one of the city’s dead­liest blazes rose to 128, and many re­main un­ac­count­ed for.

First re­spon­ders found that some fire alarms in the com­plex, which housed many old­er peo­ple, did not sound when test­ed, said Andy Ye­ung, the di­rec­tor of Hong Kong Fire Ser­vices, though he did not say how many were not work­ing or if oth­ers were.

The blaze jumped rapid­ly from one build­ing to the next as foam pan­els and bam­boo scaf­fold­ing cov­ered in net­ting ap­par­ent­ly in­stalled by a con­struc­tion com­pa­ny caught fire.
