How would Lugnica (and all other countries) react to Reinhard's death? [Spoiler Discussion]

Title. Reinhard is easily considered the strongest human being in the Re:Zero universe, so I wonder if he appeared dead out of nowhere in the capital's square (with clear signs of combat) for example how everyone would deal with the situation and the panic it would cause everyone. And yes, I saw the last episode of the anime and that is the reason for my question.
