GAZA CITY, GAZA - MAY 29:  Members of the Ezzedine al-Qassam Brigades, Hamas' armed wing, parade in Rafah, southern Gaza Strip, on May 29, 2014. Palestinian President Mahmoud Abbas on Thursday officially asked Rami Hamdallah, who is currently serving as premier within the West Bank-based government, to form a new national unity government. Last month, Hamas, which rules the Gaza Strip, and Fatah, which rules the occupied West Bank, hammered out a reconciliation deal with a view to ending the rifts that have marred their relations since 2007.
