Fatah's al-Aksa Martyrs' Brigades threatened Monday night to kill all of Hamas's leaders, including Prime Minister Ismail Haniyeh as well as Hamas Politburo chief Khaled Mashaal.

In a message sent to news agencies, the group said that it considers Mashaal, Interior Minister Sayid Siam and another high-ranking member of the ministry, Yosef al-Zahar, responsible for the deaths of Palestinians killed over the last two days during Hamas-Fatah clashes.
