It was signed in Cairo by new Hamas deputy leader Salah al-Aruri and Azzam al-Ahmad, the head of the Fatah delegation for the talks, at the headquarters of Egypt's intelligence service, which oversaw the negotiations.
The meetings in Cairo are centred around implementing the 2011 Cairo Agreement between the two political parties, in hopes of ending the 10-year political schism.
Earlier Thursday, Hamas political chief Ismail Haniyeh confirmed that the two factions had hammered out a reconciliation agreement following a week of intense discussions in Cairo.
Since that seizure of power, Hamas - which is considered a terrorist organisation by both Israel and the United States - has ruled Gaza while Fatah, led by Palestinian figurehead Mahmoud Abbas, has controlled the West Bank. In 2014, the sides agreed to create a unity government, but no such government was ever formed. In June 2007, its militants seized power in the Gaza Strip.
