Sa'ad Dawabsheh, the father of Ali - the Palestinian baby who died in an arson attack on his family's house last Saturday - has died from burn injuries in the hospital where his wife and four year old son are also being treated.
His brother told Al Jazeera the 32-year old father died in Soroka hospital on Saturday morning.
The father suffered from second degree burns after Jewish settlers attacked the family home in the Israeli occupied West Bank. His wife and elder son were previously considered to be in more serious conditions as they have third degree burn injuries.
"[Ali's] mother and brother also remain at the hospital. They both remain in very serious condition,” said Al Jazeera reporter Imtiaz Tyab.
"In fact the mother's condition for several days was thought to be worse than the father's so the fact that he succumbed to his wounds raises a lot of concern about her," Tyab added.
Jewish settlers fire bombed the Dawabsheh family home last Saturday. Sa'ad managed to save his wife, Riham, and their eldest son, Ahmad, but not the 18-month-old Ali.
The same settlers that carried out the attack also spayed graffiti on the house using the infamous “price tag” tactic with words written in the Hebrew language translating to “revenge” and “long live the Messiah,” according to reports.
Four Jewish settlers were seen fleeing the scene towards the settlement of Maaleh Ephraim, local resident Mesalem Daoubasah said.
Israeli Prime Minister Benjamin Netanyahu has said that he was shocked to hear about the attack.
“I am shocked by this horrific, heinous attack. This is a terror attack in every respect. The State of Israel deals forcefully with terror, regardless of who the perpetrators are,” he stated after the attack occurred.
Sa'ad Dawabsheh's funeral is expected to take place on Saturday in Duma.
