The text threatened to "slaughter" Israel's West Bank settlers.
Violence has also flared in the West Bank, which has seen regular clashes between Israeli troops and Palestinians.
Since Oct. 7, Israeli troops have killed at least 141 Palestinians in the territory, including 43 children, according to U.N. figures.
