Reuters news agency cited Palestinian medics saying that Israeli strikes hit several homes in northern and southern areas of Gaza.
The death toll cannot be independently verified.
IDF conducting limited ground operation
Israel’s military has not yet commented on the latest developments but said on Wednesday that troops had begun “targeted ground activities in central and southern Gaza” to expand a security buffer zone.
The Israel Defense Forces (IDF) said that troops “took control and re-extended their control to the center of the Netzarim corridor.”
Israeli forces had withdrawn from the corridor, a military zone that divides Gaza into northern and southern halves, as part of the ceasefire agreement in January.
The IDF also denied reports that it had struck a UN compound in Deir el Balah in which the UN Office for Project Services (UNOPS) said at least one staffer was killed.
Israel resumed strikes on Tuesday in which more than 400 people were killed, according to Gaza’s Hamas-run health authorities.
