It's really unclear. They shot down 4/5, the 5th which had cluster munitions (themselves unacceptable to use on anything but large columns of armor and troops and even then the risk of unexploded ordinance from them makes their use if not a war crime at least borderline because they will be killing civilians after a conflict) veered off course according to Russia and blew up over a crowded beach.

The problem here is why it veered off course. Of course Ukraine defenders would probably claim it was damaged and veered off because of that, on the other hand we know for a fact that if they can't find anything else to hit the Ukrainians have admitted to steering munitions into civilians and maybe this was a case of them veering off the last one so it wouldn't get shot down and deciding to hit civilians instead. We just don't know. What we do know is if the US was intimately involved then they're responsible. Further that the US/NATO supplied the weapons. Further that they've never stopped supplying weapons despite knowing for years they're used in terrorist attacks on civilians.

They official Russian statement says that 5 missiles were launched, 4 were shot down, and the fifth detonated over the beach and released its cluster bombs.

The article mentions that additional missiles were shot down, but it sounds like at least one hit where it was aimed.
