Iran questions nuclear deal deadline as talks 'hit wall'

GENEVA/PARIS (Reuters) - Iran, after talks with senior U.S. officials, questioned whether a July deadline for a nuclear deal with world powers will be met, fuelling doubts on the outcome as France spoke out, saying talks on curbing Tehran's uranium enrichment had "hit a wall".

Iran's talks with six major powers on curbing its nuclear programme in exchange for an end to Western sanctions could be extended for six months if no deal is reached by a July 20 deadline agreed by all parties, a senior Iranian official said.
