The girl, who was born from the womb of her dying mother in a hospital in Gaza after an Israeli airstrike, died after only a few days of life, the doctor who cared for her said, Reuters reported.
The baby was named Sabrin al Rou. Another name means "soul" in Arabic.
Her mother, Sabrin al-Saqani (al-Sheikh), was seriously injured when an Israeli strike hit the family's home in Rafah, the southernmost city in the besieged Gaza Strip, on Saturday night.
The Israeli attack also killed her husband, Shukri, and their three-year-old daughter, Malak.
Sabrin al Sakani (al Sheikh), who was 30 weeks pregnant, was rushed to the Emirati hospital in Rafah. She died from her wounds, but doctors managed to save the baby by caesarean section.
However, the baby had respiratory problems and a weak immune system, said Dr Mohamad Salama, head of the neonatal emergency department at the Emirates hospital, who cared for Sabrin al-Ru.
She died yesterday, and her little body was buried in the sandy cemetery in Rafa.
"The other doctors and I tried to save her, but she died. It was a very difficult and painful day for me personally," he told Reuters by phone.
"She was born before her respiratory system was mature and her immune system was very weak and this led to her death. She joined the family as a martyr," Salama said.
More than 34.000 Palestinians, many of them women and children, have been killed in the six-month war in Gaza between Israel and Hamas militants, the Gaza health ministry said. Israel denies that it has deliberately targeted civilians in its campaign to root out Hamas.
A large part of Gaza has been destroyed by Israeli bombardment and most hospitals in the enclave have been badly damaged, while those that are still operating lack electricity, medical equipment for sterilization and other supplies.
"The grandmother (Sabrin al Rou) called me and the doctors to take care of her, because she would be someone who would keep the memory of her mother, father and sister, but it was God's will for her to die," Salama said.
Her uncle, Rami al-Sheikh Jouda, sat by her grave today mourning the loss of the baby and others in the family. He said he visited the hospital every day to check on Sabrina al-Rou's health. The doctors told him he had a respiratory problem, but he didn't think it was that bad, until they called him from the hospital and told him the baby had died.
"Ru is gone, my brother is gone, his wife and daughter are gone, his son-in-law is gone and the house that brought us together is gone," he told Reuters.
"We have no memories of our brother, his daughter, or his wife. Everything is gone, not even their pictures, not even their mobile phones, we couldn't find them," said the uncle.
