Rabbi Chaim Kanievsky, one of the leading haredi authorities on Jewish law, instructed members of the United Hatzalah paramedic organization not to treat injured terrorists in a meeting Thursday.
From Arutz 7:
Heads of the organization arrived at the Rabbi’s house, and after receiving his blessing inquired as to the halachic issues involved in treating terrorists at the site of terror attacks.
The Rabbi clarified that in cases in which it is clear to the paramedics who among the wounded is the terrorist, paramedics should not treat the terrorist before those wounded in the attack – even if the terrorist is more seriously injured.
Furthermore the Rabbi instructed that if the terrorist was in a life threatening condition, they should leave him or her to die.
