The latest casualties were reported amid continued violations of the ongoing ceasefire, with Israeli strikes targeting several areas of the besieged territory.
A local medical source told media that at least one Palestinian was killed when an Israeli drone targeted a tent sheltering displaced people in the Al-Mashahra area, east of Gaza City.
Meanwhile, a medical source at Nasser Hospital in Khan Younis said the bodies of three Palestinians were brought to the facility following an Israeli strike near the Al-Mutahain Junction in Al-Qarara.
Eyewitnesses said two of those killed were brothers, while the third victim was their cousin. All three belonged to the Abdeen family.
Separately, another Palestinian was killed in an Israeli strike in the Sabra neighbourhood, southwest of Gaza City.
The latest attacks have added to the continuing civilian casualties in Gaza, where displaced families remain vulnerable to violence despite the ongoing ceasefire.
