The newborn baby of a pregnant woman who died with her 12-year-old daughter in a car accident on Saturday died in the hospital on Tuesday morning.Medical teams were able to birth the unborn child of Irena Rosenberg, who was at an advanced stage of pregnancy, but the baby passed away after three days of intensive care. The hospital had reported on Sunday morning that the chances of the baby surviving are slim."The chances of survival after such a prolonged resuscitation are very slim, but we are still fighting for his life," said Sheba Hospital Deputy Director Dr. Yuval Levy.The accident involved a commercial vehicle and a private vehicle, near the Ben Shemen interchange. According to initial findings of the investigation, it appears that Rosenberg's partner was driving the vehicle and swerved out of his lane into the safety rail for an unknown reason. When he tried to return to his lane on the highway, the commercial vehicle crashed into the car from behind.In addition, a 65-year-old man and an 8-year-old girl were evacuated to Belinson and Sheba hospitals in moderate and stable condition, with bruises to their torsos. Six additional people in mild condition were treated, three of whom were children.Anat Rosenberg, Irena's 12-year-old daughter who was also killed in the accident, attended Rodman Middle School in Kiryat Yam. The school will be opening its doors despite the holiday for any student wishing to speak with the educational staff and with psychological advisors."This was a very difficult car accident," said emergency medic Daniel Dakloh. "Two private vehicles stood on the side of the road with a commercial vehicle on its side crushing them. Two people were injured, aged approximately 12 and 30, with multiple systemic injuries, no pulse and no breath."Maariv contributed to this report.
