Allowances for abortion in traditional Jewish halachah follow the pattern of taking any other human life; there must be a mortal danger, otherwise it is just murder or at least manslaughter.
The Seven Laws of the Children of Noah, the traditional Jewish rules for non-Jews, have a strong and specific prohibition of abortion.
There are very different interpretations by modern rabbis. Only the Hasidic Jews still observe the strict laws against abortion. Nearly every one of my female Jewish relatives have had abortions, and brag openly of the fact. I wonder how their living children feel about this.
