July Deadline For Iran Nuclear Deal Appears In Jeopardy: Envoys

(Reuters) - It is increasingly unlikely that six world powers and Iran will meet their July 20 deadline to negotiate a long-term deal for Iran to curb its nuclear program in return for an end to economic sanctions, diplomats and analysts say. In theory, an extension to the high-stakes talks should not be a problem if all sides want it. But President Barack Obama would need to secure Congress' consent at a time of fraught relations between the administration and lawmakers.
