Washington, Dhu-AlQa'dah 17, 1435, Sep 12, 2014, SPA -- The United States will consider rolling back sanctions against Russia if a 12-point peace plan for the conflict in Ukraine agreed earlier this month is fully implemented, a senior US official says, according to dpa. Washington has told Moscow that the measures in response to its actions in Ukraine will be lifted once all elements of the Minsk peace plan are implemented, the official says on condition of anonymity. -- SPA 18:12 LOCAL TIME 15:12 GMT www.spa.gov.sa/w
