Four Palestinians, including a father and his child, were killed and more than twenty residents were injured, since Thursday at noon, as the army carried out several air strikes targeting Gaza.

Palestinian resistance groups retaliated by firing more than 16 homemade shells and mortars into Israeli settlements adjacent to the Gaza Strip.

Hamas, along with other resistance groups in Gaza, and the Egyptian government, held Israel responsible for the latest escalation, and warned of further tension should Israeli continue its strikes.

Israel, on the other hand, held Hamas responsible for the escalation, claiming that Hamas and other armed factions are seeking further escalation.
