UN-Arab League Syria envoy Lakhdar Brahimi hopes to revamp his role as an international peace mediator in the Syrian conflict as a United Nations envoy without any official link to the Arab bloc, UN diplomats said on Tuesday. Brahimi has become increasingly frustrated with the league's moves to recognize the Syrian opposition, which he feels has undermined his role as a neutral mediator, diplomats said, reuters reported. "The joint special representative feels that the Arab League approach makes it difficult for him to carry out his mandate," a diplomat said. "He feels that it would be best to be associated only with the United Nations at this point to ensure his neutrality." Another UN diplomat confirmed the remarks. There have been rumors circulating for weeks that Brahimi might resign, though diplomats said his preference was to remain involved in Syrian peace efforts through the United Nations, an organization he has worked with for decades. Brahimi will present an update to the UN Security Council on Friday about the situation in Syria's two-year-old civil war, which the UN says has claimed more than 70,000 lives. "We expect Brahimi to offer another bleak report," a diplomat said. The Arab League has suspended Syria's membership and last month invited opposition leaders Moaz Alkhatib and Ghassan Hitto to attend a summit in his place. The Syrian National Coalition, an opposition bloc recognized by the Arab League as the sole representative for conflict-torn Syria, opened its first embassy in Qatar last month in a diplomatic blow to President Bashar al-Assad.
