"We are sounding the alarm: Israel continues its campaign leading to crimes against humanity in Gaza," RIA Novosti quoted the experts as saying, which was released by the Office of the UN High Commissioner for Human Rights (OHCHR).
The statement also refers to the risk of genocide against the Palestinian people.
Earlier, Israeli Defense Minister Yoav Galant met with the IDF military and told them that an order to enter the Gaza Strip would soon arrive.
Reuters previously wrote that Israel's military operation "Iron Swords" in the Gaza Strip will be characterized by "unprecedented ferocity."
American journalist Seymour Hersh expressed the opinion that Israel intends to arrange a semblance of the destruction of Japanese Hiroshima on the territory of the Gaza Strip, only without the use of nuclear weapons.
