WASHINGTON, Nov 8 (Reuters) - Envoys of the "Quartet" of Middle East peace mediators will meet separately with Israeli and Palestinian officials on Nov. 14 in Jerusalem, their latest effort to jump-start the stalled peace process, the U.S. State Department said on Tuesday.

"We expect these will again be Quartet envoy meetings with the parties separately," State Department spokeswoman Victoria Nuland told a news briefing, saying the meetings would seek to encourage both sides to offer concrete proposals on land and security concerns.

The Quartet is made up of the United States, Russia, the European Union and the United Nations.
