A four-month old boy suspected to have sustained injuries from parental abuse, died on Sunday after being declared brain dead late last week.
The infant was hospitalized with broken bones at the Sheba Medical Center, Tel Hashomer last week, along with his twin sister who was in stable condition.
The parents and grandmother of the infant twins were arrested last Tuesday on suspicion of child abuse.
The four-month-old twins, a boy and a girl from Ramat Gan, have been hospitalized for about a week with internal hemorrhaging and fractured bones in the Sheba Medical Center at Tel Hashomer.
Detectives arrested the twins' parents and grandmother, who were tending the babies in the hospital, after doctors at the Safra Children's Hospital diagnosed the infants had most likely been shaken vigorously by an adult.
The baby boy's condition is still critical, while his twin sister's condition is moderate, the hospital reported on Wednesday.
The grandmother, who looked after the twins a considerable part of the time, was released on Wednesday while the parents remained in custody. The three are to be brought to the Tel Aviv Magistrate's Court onn Thursday for the extension of their remand.
The twins' parents vehemently deny the abuse allegations and insist they love their children and look after them devotedly.
Earlier this week the parents said the boy's injuries had likely been caused by the paramedics who tried to resuscitate him. They could not explain the injuries suffered by the girl, who had not been taken to hospital by paramedics.
The father, 37, works as a D.J. and was formerly involved in making a film about police work that was broadcast on cable television.
High-profile attorney Zion Amir, who represents the couple, said on Wednesday "the parents will continue to cooperate fully with the police and help advance the investigation. They are deeply dismayed by their beloved children's condition. They believe the findings will ultimately correspond with their version."
"This is the middle ground between an accident and abuse," said Yitzhak Kadman, executive director of the National Council for the Child. "Most of the parents who shake their children don't mean to harm or abuse them, and are unaware of the damage they might be causing as they try to make the child stop crying," he said.
