GENEVA (Reuters) - U.N. Special Envoy Staffan de Mistura said on Tuesday after talks with Russia, Iran, and Turkey that "there is an extra mile to go" in the "marathon effort" to ensure a credible, balanced and inclusive constitutional committee for Syria.

De Mistura, addressing a news conference, said that he would report to U.N. Secretary-General Antonio Guterres on Wednesday and to the Security Council on Thursday and expected his successor Geir Pedersen to build on his work from Jan. 7.
