Agreement edges closer to resolution

Teheran negotiator cautions that 'some issues still remain unresolved'

Iran and six world powers were close to clinching a historic pact on Monday that would bring Iran sanctions relief in exchange for curbs on its nuclear program, but an Iranian negotiator said he could not guarantee a deal was imminent.

"I cannot promise whether the remaining issues can be resolved tonight or tomorrow night. Some issues still remain unresolved and, until they are solved, we cannot say an agreement has been reached," Iran's Tasnim news agency quoted Deputy Foreign Minister Abbas Araqchi as saying in Vienna.
