I thought the same. What an odd statement from a space agency.
Even the article title downplays it. Why is the headline "smoke alarms go off" as opposed to "something was on fire" (aka visible smoke and burning smell). Smoke alarms going off can be a false detection.
The news here is something was literally burning on the ISS and the secondary news is that according to the relevant space agency they didn't even find out what it was before going back to sleep.
