After meeting with Arab League chief, Amr Moussa in Cairo on Wednesday, Palestinian Authority Prime Minister Ismail Haniyeh repeated what Hamas' Damascus-based top leader Khaled Mashaal said on Saturday, demanding the "establishment of Palestinian state, with June 4, 1967 borders, with east Jerusalem as its capital, and right of return of Palestinian refugees." "The right of return of Palestinian refugees is holy, no Palestinian can make concessions about it," he added.
