Resolves once the death count no longer seems too contested.
No Wikipedia update to the estimates of death totals has occurred for a while; even if the 471 number is rejected the totals would be at least 200, and the actual number is also higher. The Wikipedia discussion appears to be entirely about whether there is a a reliable unbiased source that says there is no dispute as to the source of the munition.
Only one source has a range below 200 at this time, and that’s 100-300. It seems likely that any further attempts to count the dead will not be able to distinguish those killed from the explosion in question from ones killed later.
