IFAIK modern Orthodox would not have a problem driving a pregnant woman in labor to a hospital, or telephoning for an ambulance for her, on a holiday or sabbath. Actions otherwise forbidden would be allowed if the likely result would be to save a life.
I agree.
It would be a sin NOT to take her to the hospital.(JMHO)
On the other hand, the evil bastards who attacked her should burn in hell for an eternity.
