There have been numbers as high as 90k reported initially, so I wouldn't say it is "moving up" across time but across sources. There is no clear data, but at this point 30-32k appears to be the lower bound estimate over which there's a consensus. Likely to be higher.
It’s just an NPC accusation thrown at Iran to justify killing millions of civilians. Why even entertain this shit from people who are just pretending to care about it. Everyone knows what they want to do is raze Iran.
Maybe, but I distinctly remember the numbers 15 up to 30k two weeks ago from the UN Iran watchdog.
Then a week ago, a US-based watchdog let the number 35k float, and all of the sudden that's the number used by US department of state. And now the number you just threw is 40k.
Meanwhile, the OSINT community confirmed deaths are still around 15k. I will admit, the bombing doesn't help because we cross data from funerals and morgues/hospitals, and now we will have to distinguish bombing victims from repression victims, which in some areas (southeast and west mostly) is difficult.
