Is a long-term truce between Israel and Hamas in the offing?Khaled Mashaal, the head of the Palestinian Islamist movement's political bureau, confirmed on Friday that the two sides are engaged in indirect discussions on a possible cease-fire in the South. "There is talk between the two sides," Mashaal told the London-based Arab-language daily newspaper Al-Araby al-Jadid. "As of this moment, the talks are moving in a positive direction, but they have yet to mature into an agreement."Mashaal confirmed earlier reports that one of the intermediaries in the negotiations between the two sworn enemies is former British prime minister Tony Blair. The proposals raised during the discussions included variations of cease-fires and truces that would theoretically span years.
