Haniyeh’s visit came in response to a special invitation from Cairo, in advance of a broader meeting of Palestinian factions that could begin as early as next week, Hamas spokesman Hazem Qassem told Reuters.
Egypt has played a major role in the brokering of a ceasefire which ended 11 days of war erupted on May 10.
More than 250 Palestinians were martyred in hundreds of Israeli air strikes on Gaza during that conflict. Rockets fired by Palestinian Resistance in Gaza killed 13 Israelis.
Haniyeh and Egyptian officials will discuss the truce as well as reconstruction plans for Gaza, Qassem said. Egypt has said it will allocate $500 million for the reconstruction.
Egyptian authorities hope to meet members of Hamas’ rival Fatah, including Palestinian President Mahmoud Abbas, the Egyptian sources said.
A delegation from Fatah led by Jibril Rajoub is expected in Cairo in the coming days, a Palestinian official said.
