The milestone comes as a fragile US-brokered ceasefire largely holds, but with both sides accusing the other of violating the terms of the deal.
In a statement, Gaza’s health ministry said the death toll from the war had risen to 70,100.
The ministry added that since the ceasefire came into effect on October 10, 354 Palestinians had been killed by Israeli fire.
Despite the ceasefire, the Palestinian territory remains in a deep humanitarian crisis.
