One of the attacks targeted a school sheltering displaced people west of Gaza city, killing at least four Palestinians.
The Palestine Red Crescent Society said in central Gaza, the Israeli army struck a residential building in the al-Zawayda area, killing six people.
The killings came a day after the targeting of a United Nations-run school for displaced Palestinians, in which at least sixteen people were killed and dozens wounded.
The Israeli military said it attacked a Khan Younis municipality building in southern Gaza, claiming it was used by Hamas for military activity.
