The deadline expires at 6 pm American time, midnight towards Monday in Sweden, Trump writes on Truth Social.
The President describes an agreement as a "last chance" for Hamas. If the group does not accept the ceasefire, "a hell, like no one has ever seen before, will break out against Hamas".
"There will be peace in the Middle East one way or another", Trump writes in capital letters.
Donald Trump says that many of the remaining Hamas members in Gaza are surrounded and that he can give the go-ahead to "quickly extinguish" their lives at any moment.
"Fortunately for Hamas, they will get a last chance", he writes and continues:
"This agreement also spares the lives of all remaining Hamas warriors!"
The proposal for a ceasefire presented by the US and approved by Israel consists of 20 points.
The proposal means an immediate end to the war, release of all hostages held by Hamas, independent distribution of emergency aid to the population of Gaza, a step-by-step withdrawal of Israel's military and disarmament of Hamas.
