It is "apparently" because important details are unclear e.g. if the Russians placed the explosives and the Ukrainians inadvertently set them off since there was fighting in the area. Blowing up a large dam that is structurally sound is not something that happens accidentally. It would have required the Russians to place truly massive amounts of explosives at critical points within the dam's structure, which they did control at the time. That is an intentionally engineered situation. It does not imply that they intentionally or accidentally set them off. Ukraine had little capacity to do real damage to the dam. Artillery shells will not do much more than scratch the paint. The highly specialized capabilities required to do more damage are not available to Ukraine nor would the battlefield conditions have allowed them to operate these capabilities even if they did have them.
