Nostradamus predicted blood of leaders who are being (attempted to be) assassinated. May we all rise together against these forces of evil.

Blood will be split in front of the people, which will not go far from the high heavens. But for a long time it will not be heard, the spirit of a single man will bear witness to it. (IV-49)

When I say «the blood will be split in front of the people», that refers to leaders being assassinated. «But for a long time it will not be heard», refers to the fact that some of the deposed leaders’ struggles for power will occur from within. It will be a long time before the whole story is revealed. «The blood that will not go far from the high heavens» represents the leaders. You must remember that in my time kings are ordained by God, and therefore are considered to be just one step away from God. This event will be closer to the heavens than the everyday things that happen to people.

«The spirit of a single man will bear witness to it», refers to Ogmios who will put things together and realize the full impact of it all. That will fire his determination to be more than just an underground group leader. He will decide to do something to overthrow the Anti-Christ.
