'Strip Abbas' citizenship'
Gaza City - Hamas leaders have intensified their criticism of Palestinian President Mahmoud Abbas, saying they no longer consider him a Palestinian.
This harsh verbal attack could harm long-running reconciliation talks between Hamas and Abbas' rival Fatah movement.
A wide swath of Palestinian society has criticised Abbas for his decision last week to suspend efforts to have Israeli officials prosecuted for war crimes during last winter's Gaza war.
In Gaza, Hamas leader Mahmoud Zahar said on Monday that Abbas can no longer be considered a Palestinian and demanded that he be stripped of his citizenship.
Hamas and Fatah have been bitter rivals since Hamas seized Gaza in 2007, leaving Abbas only in charge of the West Bank.
