What's with the scorn quotes? Bad though the Iranian regime is, does the headline writer really suspect it was intentional, a decision to whack a particular passenger and rather than just arrest him or her while on the ground in Tehran and do the deed in a prison basement just take out 178 others with the target? And if that's not what it was, and it was really unintentional, does the headline writer suspect that the anti-aircraft battery had a technical fault, rather than it, in fact, being human error?
