The father of a Palestinian toddler killed last week when their home was firebombed by Israeli settlers died Saturday of his injuries from the attack, which triggered Palestinian protests and an international outcry.
The arson in the village of Duma in the occupied West Bank drew condemnation of Israel's failure to curb violence by Israeli settlers and prompted the government to order a crackdown on extremism.
Saad Dawabsha succumbed in hospital in the southern Israeli city of Beersheba where he was being treated for third degree burns, Palestinian official Ghassan Daghlas said.
"Saad Dawabsha died and plans are underway for his funeral," Daghlas said.
The Dawabsha family confirmed his death.
Dawabsha's wife Riham Dawabsha and four-year-old son Ahmed are still fighting for their lives in hospital after the arson attack which killed 18-month-old Ali.
A Palestinian official told AFP that before the funeral in the Dawabshas' home village a post-mortem would be held to provide evidence for a complaint to the International Criminal Court (ICC) in The Hague.
The Palestinians on Monday submitted a request to the ICC to probe the firebombing and "settler terrorism".
At a meeting with Palestinian president Mahmud Abbas on Wednesday, Arab foreign ministers agreed to call on the United Nations to protect the Palestinians from "terrorist crimes" by Jewish settlers.
The family's small brick and cement home in Duma was gutted by fire early on July 31, and a Jewish Star of David spray-painted on a wall along with the words "revenge" and "long live the Messiah".
Prime Minister Benjamin Netanyahu condemned the attack as "terrorism in every respect", and vowed to spare no effort in bringing the perpetrators to justice.
Israel this week used a controversial form of detention without trial normally invoked for Palestinians against one alleged Jewish extremist, following the outcry over the attack.
The domestic intelligence service named him as Meir Ettinger.
He was arrested in Safed in northern Israel "because of his activities in a Jewish extremist organisation", a Shin Bet spokesman told AFP.
Police said Ettinger, who is aged around 20, was suspected of "nationalist crimes" but did not accuse him of direct involvement in the firebombing.
