Saying Russia is "deliberately targeting the civilian population" is implicitly a war crime accusation, but it could very well be that the Russian officer who made the targeting decision was actually trying to hit a ball-bearing factory and accuracy just wasn't good enough. Though for FPV drones that can be retargeted in real time, such an argument is harder to make. In any case, whether or not something is a war crime depends on the state of mind of the decision makers, not just the outcome.
