JERUSALEM (JTA) – Adele Biton, a four-year-old girl who was severely injured in a Palestinian rock attack two years ago, has died.

Adele died Tuesday, Feb. 17 at Schneider Children’s Medical Center in Petach Tikvah from complications of a lung infection. She had remained in an unconscious state since the West Bank attack on her mother’s car on March 14, 2013.

Adva Biton was driving her three young daughters near the Ariel settlement when her car swerved after being hit by rocks thrown by two Palestinian teens and struck a truck. The family had been driving from their home in the West Bank settlement of Yakir to central Israel. Adele, then two, suffered a serious head wound. Her sisters, ages four and five, were moderately wounded. Last September, Adele returned home after the rehab facility said it could not do anything more for her.
