"My darling, my darling, thank God, thank God. Calm down, darling, calm down," Mohammed Hadidi is heard saying in Arabic as he consoles his child inside Gaza City's Dar Al-Shifa Hospital.
Six-month-old Omar Hadidi suffered a broken leg after an Israeli airstrike Saturday hit a three-story house in Gaza City's densely populated Shati refugee camp, killing eight children and two women from Hadidi's extended family.

Mohammed Hadidi told reporters that his wife and her brother's wife had gathered at the house with their children to celebrate the Eid al-Fitr holiday ending the Islamic holy month of Ramadan.
She and four of the children, aged 6 to 14, were killed. Only baby Omar is known to have survived.
"This is the severest of crimes. My family never launched rockets or bombed anything, they just went to celebrate Eid with their uncle and then we now come to the hospital to take their dismembered bodies," Mohammed Hadidi said outside of the hospital. "My younger child is five months, and he is now injured at the hospital. What did he do? Did he launch rockets at the Jews? Who is angry with my five-month-old son? Allah is my suffice, and the best deputy."
The blast left the children's bedroom covered in rubble and smashed the salon. Amid the wreckage were children's toys, a Monopoly board game and, sitting on the kitchen counter, unfinished plates of food from the holiday gathering.
"There was no warning ... You filmed people eating and then you bombed them?" a neighbor, Jamal Al-Naji, said, referring to Israel's surveillance over the Gaza Strip.
The Israeli military did not immediately respond to a request for comment. Hamas said it fired a salvo of rockets at southern Israel in response to the airstrike.
As of Sunday, at least 188 Palestinians have been killed in the hundreds of airstrikes in Gaza, including 55 children and 33 women. Eight people in Israel have been killed, including a 5-year-old boy and a soldier.
Despite the toll and international efforts to broker a cease-fire, Israeli Prime Minister Benjamin Netanyahu signaled the fourth war with Gaza's Hamas rulers would rage on. Hamas also pressed on, launching rockets from civilian areas in Gaza toward civilian areas in Israel.
