Palestinian President Mahmoud Abbas fired most of the governors in the occupied West Bank on Thursday, responding to long-standing demands for a political shake-up as frustration grows with the semi-autonomous Palestinian Authority. Abbas issued a decree dismissing the governors of eight provinces under Palestinian administration in the occupied territory. The upheaval included the restive northern cities of Nablus, Jenin and Tulkarem, the focus of a recent surge in Palestinian militancy that has undermined the authority’s leadership.
