The five-day cease-fire is due to end at midnight Monday, or 5 p.m. EDT. However, the extension will be announced in a statement by Egyptian negotiators in Cairo an hour before, both the Palestinian news agency Ma'am and Israel's Channel 10 television broadcaster said.
Egypt is serving as a facilitator to the peace talks.
Channel 10 said the agreement includes an easing of border restrictions in Gaza and an increase in Gaza's fishing zone in the Mediterranean Sea, adding larger issues will be considered at another peace negotiation to be convened in a month.
