Spokesman for the Israel Defense Forces (IDF), Daniel Hagari says the Israeli military will "deepen" and "increase" its strikes on Gaza.
At a press conference, he told reporters this would allow Israel to "minimise the risks to their forces in the next stages of the war" - and it would happen "from today".
Hagari also repeated a call for residents of Gaza City to move to the south of the region, saying it was for their own safety.
The warning comes on the same day aid was allowed into Gaza, from Egypt, for the first time since the Israel-Hamas war erupted.
Despite some leaders celebrating the move, the UN called the aid a "drop in the ocean" of what's needed.
It's two weeks since Hamas launched its assault on Israel, killing more than 1,400 people. Palestinian officials say more than 4,000 have been killed in Gaza since then.
