The missile - packed with more than 100kg (220lb) of explosives - did not detonate, so the damage is limited to three floors. But it's still significant.
We saw fragments of that missile, now being collected as evidence: mangled metal pieces, some with Cyrillic lettering on them, gathered in a heap.
Weapons experts we've consulted agree that it looks like a Russian cruise missile and say the damage is consistent with an Iskander striking but not exploding.
"Sometimes fuses do not work and missiles just don't detonate. [It] can happen with a lot of different systems," Fabian Hinz, a missile and drone expert at the International Institute for Strategic Studies in Berlin, told me.
"I think it hit the building," military analyst Oleksandr Musiienko confirmed here in Kyiv.
"This missile has a high speed and low altitude. It's really hard to see on the radar. And of course, we do not have still enough air defence systems like the [American] Patriots, for example, which we can use to shoot them down."
In Kyiv, the increase in early morning attacks is obvious: they've grown more frequent - but most importantly they're bigger in scale. Russia now launches hundreds of drones at a time, deliberately draining Ukraine's resources.
That's why Zelensky is constantly calling for more missiles: to someone far from Kyiv it might sound like he's stuck on repeat. But for people here it might be the difference between life and death.
Russia's strikes are not only symbolic, on empty government buildings. They regularly hit people's homes, too, as we saw again this week.
"Sometimes a lot of these drones are decoys - without explosives - just to weaken our air defence systems," Mr Musiienko explained.
"We have never seen such attacks ever in our history. Of course, it's a threat."
Closer to the front line, the tactics are different: deadly glide bombs arrive almost without warning.
In Yarova, those killed this time were elderly. They're the people who are most reluctant or least able to leave their homes, even as the fighting moves close again. The village was occupied by the Russians at the start of the full-scale invasion in 2022, then liberated later by Ukrainian troops.
At least 24 people who survived all that are now dead.
Images from the scene show their bodies sprawled on the ground and a smashed-up post office van that had been delivering the pensions. It parked under a tree for cover, hoping not to be seen - but the bomb hit anyway.
Ukraine's Foreign Minister Andrii Sybiha called it a "barbaric" strike by Russia and a "heinous crime" against the very people and region Putin claimed needed saving when he ordered the invasion.
"We urge the world to speak out and act immediately," Sybiha said.
