The announcement caused the explosion?
WTF?

No. It created the explosion.
Yeah, it reads weird to me, too. Must have been an envelope with confetti or other party junk that “went off” (as intended, I imagine) when opened up and something in the envelope (or package) struck and killed her.
Within the last year or so, one women was killed when her espresso maker blew up and a piece of metal hit her head. Another man was killed when his e-cigarette/vaping device blew up and the mouth piece broke off and cut his jugular.
