No, it's a very specific thing and not at all applicable here. Blood libel was something along the lines of "the Jewish people are murdering children to use their blood for secret ceremonies"[0]. The "libel" part should give it away - it doesn't apply to someone revealing true facts.

The people calling it blood libel because the facts are inconvenient and make Israel look bad are being disingenuous.
