This is more strategic bombing than terror bombing though. Terror bombing would be, for example, targeting apartments, or things like that. This is a warehouse that is used by a company supplying goods to the military.
Not necessarily. Like I said elsewhere in this thread, if a company makes guns for the enemy military and toys children in different factories, only the gun factory would be legal to bomb; bombing the toy factory would still be a war crime despite the shared ownership. Similarly, it's on Ukraine to prove that the warehouses they bombed were being actively used to supply the Russian military in quantities justifying the loss of life and property.
Russia didn't agree to the same rules, so Ukraine shouldn't have to follow them when defending from them.
Civilians, who are (especially in a colonial autocracy like Russia) third parties not directly involved in the conflict, don't suddenly have their rights waived because the armed gang ruling over them are pieces of shit. That's collective punishment, and even without international law it's the sort of thing we always recognize as psychopathic when done to anyone we don't already hate. "People shouldn't be punished for things they didn't do" is ethics 101. A given rule could be up for discussion if sticking to it would seriously hamper Ukraine's war effort, but that's not what's going on here. Either the Wildberries warehouses bombed were significant contributors to Russian logistics, in which case they're legal to bomb anyway, or they're not and bombing them does nothing to advance the Ukrainian war effort, and the Ukrainian military, as the ones doing the bombing in this case, have a responsibility to prove the former is the case.
If Ukraine follows all the international laws then they're fucked. If Ukraine follows all the international laws then they're fucked. For example, antipersonnel mines are banned by international law.
Things that would make one fucked if not done are generally not banned under international law. As for your example, anti-personnel mines aren't banned under international law. There's a treaty to ban them, but that's a different story.
I'm not sure how many dies, if any, but it won't be a large number.
The article doesn't give total numbers, but it does list plenty of death and injury.
Ukrainian drones have hit warehouses of Russia's biggest online retailer again, killing one person and injuring another 14, local officials say.
Ukraine hit the retailer's warehouses in central Russia four days ago, killing eight people, according to Russian officials.
In Krasnodar, 10 people were injured in an attack on a warehouse complex, with three in a serious condition, the region's Governor Veniamin Kondratyev said.
He later said that a young woman died of her injuries in hospital.
Five people were hurt in a warehouse complex on the outskirts of Nevinnomyssk, Stavropol Governor Vladimir Vladimirov said.
Also, it's not like ruining people's livelihoods is exactly kosher without clear military value.
It will prevent or slow down purchases though. It won't really galvanize them, rather it'll annoy them.
Things being on fire tends to galvanize people against the people setting things on fire even if nobody was dying (which is not the case here), and you can bet that Russian media will amplify the damage done to small businesses.
The goal is to put pressure on civilians.
Then actions taken primarily in service of that goal are war crimes, plain and simple. Anything negative with "civilians" in it as the primary goal of a military action is pretty much guaranteed to be a war crime, because protecting civilians from armed reprisal is half the point of international law.
If they wanted to hurt civilians they would have hit a power station near Moscow.
Or it could be that they couldn't find an excuse to bomb those. Besides, they're bombing oil infrastructure instead, which seems to have pretty much the same effect (while still having a clear military purpose).
