Gaza authorities said more than 1,400 Palestinians, mainly civilians, including children, have already been killed and more than 6,000 wounded.
In quotes published by Hamas, deputy Hamas chief, Saleh Al-Arouri, said: "The plan was to target the army's Gaza team and fight occupation soldiers only."
U.S. President Joseph Biden had suggested on Wednesday that he had seen images of children beheaded by militants.
But medics, international human rights organisations and journalists have documented that militants killed women, children and the elderly as well as young men and soldiers in their rampage.
Foreign reporters shown sites targeted by Hamas, witnessed ruins of burnt-out houses and streets scattered with dead residents and militants.
