(Adds further detail) NAIROBI, Nov 17 (Reuters) - Environment ministers at U.N. climate talks agreed on Friday to a review, ending in 2008, of the U.N.'s Kyoto Protocol for fighting global warming, in a big step towards breaking deadlock at the meeting, a minister said. "I think it's agreed," German Environment Minister Sigmar Gabriel said after meeting other ministers for high-level talks before putting the issue to a vote. "We've reached a compromise where we have a review and it should end in 2008," he said, adding: "You don't know what will happen" when all 189 nations meet in a plenary later on Friday. He said that China had dropped objections to a text after changes on the final day of the talks. A Russian proposal for allowing new countries to sign up for cuts in greenhouse gas emissions was still unresolved.
