Earlier the talks were planned to be resumed Thursday.
"The national Palestinian dialogue will resume in Cairo in the first days of April immediately after a summit of the Arab League in Doha," a high-ranking source in the Egyptian leadership told the agency.
The sides are expected to coordinate a number of serious issues unresolved during the two previous rounds of dialogue, including a program for the future government, election law, as well as the status of the Palestine Liberation Organization (PLO) and participation by the Hamas and Islamic Jihad movements in the PLO.
Hamas has held power in Gaza since 2007, while Fatah, led by Palestinian President Mahmoud Abbas, controls the West Bank.
Fatah has renounced violence, while Hamas refuses to recognize Israel and reserves the right to use violence in its struggle to create a Palestinian state.
The rival movements resumed contact only after the three-week Israeli military onslaught in Gaza that ended in January, leaving about 1,300 Palestinians dead. The attack was launched in retaliation for homemade rockets launched by Gaza militants.
