The mother of Palestinian toddler Ali Saad Dawabsha, who was killed when suspected Jewish extremists firebombed his house, succumbed to her injuries on Sunday night, said the Israeli hospital where she was cared for and her family.
Several suspects have been arrested after the family's home in the West Bank village of Duma was firebombed with Molotov cocktails on July 31, sparking anger among the Palestinian community.
"Riham Dawabsha died in the night," a spokeswoman for the Tel Hashomer Hospital in Tel Aviv told AFP, where the 26-year-old teacher was admitted with third-degree burns covering 80 percent of her body.
Anwar Dawabsha, a family member, confirmed he had been informed of her death and said the funeral would be held on Monday in Duma.
Riham Dawabsha's death comes after her 18-month-old Ali died on the day of the attack and his father Saad eight days later. Ali's four-year-old brother Ahmed is still in hospital.
The Israelis are expected to return Riham's body to the Palestinian authorities to a checkpoint at the entrance to the occupied West Bank, from where it will be taken to her village.
The bombing of the family's home came only hours after a stabbing attack at a Jerusalem Gay Pride march that killed a 16-year-old girl and wounded five other people.
While the attacks were not related, both have led to criticism of Israel's government and security forces, who have been accused of failing to properly address Jewish extremism.
