No, it did not happen the way he described it. Firstly, there was a baby, not babies. Secondly, the child was not secreted somewhere alone, found after the parents had been shot and then deliberately killed.
Netanyahu is deliberately embellishing the story in order to heighten the outrage over October 7th, and then trying to frame anyone protesting Israel’s ethnic cleansing in Gaza as a supporter of what happened. It’s disgraceful.
