The sources reported on Wednesday that rescue efforts are still ongoing, and the casualties include women and children.
The recovered victims were all transferred to Al-Aqsa Martyrs Hospital in the city of Deir el-Balah, the sources added.
Eyewitnesses told Xinhua that an Israeli warplane fired several missiles at the house sheltering several displaced families.
The massive blast brought down the building and caused severe damage to neighboring houses in the western part of the camp.
Meanwhile, the Palestinian death toll from Israeli strikes in the Gaza Strip has risen to 29,313, with 69,333 others wounded, as the Israel-Hamas conflict continues, the Gaza Health Ministry said in a press statement on Wednesday.
