Tensions between Fatah and Hamas have been increasing daily, in light of security measures taken by Fatah's Palestinian Authority (PA) in the West Bank since early July, such as the arrest and summoning of Hamas activists. And in early August, Hamas made serious statements against Palestinian President Mahmoud Abbas.
In an Aug. 12 press statement, Mahmoud al-Zahar, a member of Hamas’ political bureau, ruled out a reconciliation between those who fight Israel (meaning Hamas) and those who cooperate with it (referring to Fatah) and said Abbas would lose any future elections. Zahar did not name either Hamas or Fatah directly, however.
