Hamas warned on Tuesday that Palestinian President Mahmoud Abbas’ delay in easing sanctions on Gaza was putting at risk a unity deal signed last week, AFP said. “The continuation of the punitive measures against our people in Gaza a month after the dissolution of the administrative council spoils the general atmosphere for reconciliation,” a party spokesman told Hamas media. Hamas is due to hand over Gaza’s border crossings by November 1 ahead of a full transfer of power by December 1. The Palestinian Authority’s top border official visited Gaza on Monday.
