Are non-Jews permitted to have abortions? (Consider the gemara in Sanhedrin 57b where "a baraita brings in the name of Rabbi Yishmael that a Ben Noach gets capital punishment if he intentionally causes an abortion, which he derives from a pasuk. Rashi takes the simple understanding of the gemara that this prohibition applies only to a non-Jew, whereas for a Jew the prohibition of murder only applies to a baby once he/she is born.")
Edited in response to msh210's comment: I'd be interested in knowing both whether non-Jews may have abortions and, perhaps more interestingly, whether they may perform them (see the source above). Would there be any special considerations for a non-Jew performing an abortion on a Jew?
