MOSCOW (Reuters) - U.N.-Arab League peace envoy Lakhdar Brahimi expressed regret on Monday that a U.N.-brokered truce had not been more successful in Syria but said he would not let this discourage his peace efforts.

Brahimi also said after talks with Russian Foreign Minister Sergei Lavrov in Moscow that there was no immediate plan to send U.N. peacekeepers to the Middle East country.
