Under heavy Israeli pressure, Egypt on Thursday indefinitely postponed a planned U.N. vote on a proposed Security Council resolution that sought to condemn Israeli settlement construction in the West Bank and east Jerusalem, diplomats and Western officials said, just a few hours before the vote was set to take place. The vote would have been one of the last opportunities for President Barack Obama to take a stand against Israeli settlement building after years of failed peace efforts, but doing so could re-ignite a dispute with a close ally in the waning days of his tenure.
