Just weeks after the arrest of alleged Jewish terrorist, Yaakov Teitel, a West Bank rabbi on Monday released a book giving Jews permission to kill Gentiles who threaten Israel.

Rabbi Yitzhak Shapiro, who heads the Od Yosef Chai Yeshiva in the Yitzhar settlement, wrote in his book "The King's Torah" that even babies and children can be killed if they pose a threat to the nation.

Shapiro based the majority of his teachings on passages quoted from the Bible, to which he adds his opinions and beliefs.

"It is permissable to kill the Righteous among Nations even if they are not responsible for the threatening situation," he wrote, adding: "If we kill a Gentile who has sinned or has violated one of the seven commandments - because we care about the commandments - there is nothing wrong with the murder."

Several prominent rabbis, including Rabbi Yithak Ginzburg and Rabbi Yaakov Yosef, have recommended the book to their students and followers.
