George Mitchell resigns as US Mideast envoy

There are no imminent plans to announce a replacement for Mitchell, the officials said, although his staff is expected to remain in place at least temporarily.
Mitchell’s resignation comes at a critical time for the Middle East, which is embroiled in turmoil, and the Israeli-Palestinian peace process, which has been moribund since last September and is now further complicated by an agreement between Palestinian factions to share power.
