Riham al Dawabsheh, the mother of a Palestinian toddler who was burned to death in an arson attack by a number of Israeli settlers on their house, succumbed to her own wounds Saturday.

Riham, 27, suffered burns to 90 percent of her body. She was receiving treatment with her other son at an Israeli hospital.

Riham's father said her blood pressure had dropped to life-threatening levels. She was clinically dead, her father said.

Riham's younger son, Ali, was killed in the arson attack on their house in Duma on July 31. Her husband, Saad Dawabsheh, succumbed to his injuries on August 8.

Ahmed Dawabsheh, the older son, is still receiving treatment at hospital.
