Hamas leader Khaled Meshaal is in Egypt to hold talks with Egyptian and Arab League (AL) officials on Palestinian reconciliation efforts.
"Hamas is committed to achieving reconciliation to end the Palestinian division, form a government, hold elections and release all detainees," Meshaal said after meeting with Arab League chief Nabil al-Araby in Cairo on Friday.
In December, the Hamas Political Bureau chief met with acting Palestinian Authority Chief Mahmoud Abbas, who heads the Fatah party, in the Egyptian capital.
The two then agreed on a process that would pave the way for the Islamic group to join a reformed Palestine Liberation Organization, which includes Fatah, and for long-delayed Palestinian elections.
The deal came months after the two factions signed a reconciliation deal in Cairo which has yet to be implemented.
In 2006, Hamas won a sweeping victory in the general elections in the Palestinian territories.
But the Hamas-led government soon faced what it saw as a coup plot by rival Fatah, which established its own government in the West Bank city of Ramallah, leaving the Islamic movement with control of the Gaza Strip.
The breakthrough in the Palestinian reconciliation process has seriously concerned Israel, which has threatened not to enter into any negotiations with a unity Palestinian government.
