If it's russian cruise missiles (as some people claim) - then it was on purpose. In that case it's Russia testing NATO resolve in defending Eastern Europe. In that case NATO must respond strongly or Russia will escalate quickly. Others claimed it's S-300 (anti-air missiles). Ukraine uses them to defend against russian missiles (they should self-destruct when they miss but sometimes they malfunction and they are very fast so they can hit random places far away). These same S-300 missiles are also used by Russia against ground targets (they are low-accuracy in that application cause you can only correct them with radar at the starting phase). If there were 2 S-300 missiles it's more likely it was Russia cause it's very unlikely 2 anti-air missiles missed their target and landed near each other (and self-destruct mechanisms failed in both). It could also be a russian missile that got damaged by Ukrainian anti-air missiles and missed. We just need to wait for more information, no reason for knee-jerk reactions.
