Big hurdles to Iran nuclear deal as deadline looms
As a June 30 deadline for a final nuclear deal approaches, major differences remain between Iran and world powers on several key issues including sanctions relief and UN access to Iranian sites, a senior Western diplomat said on Friday.
"The most difficult subjects need to be resolved in the coming days," the diplomat told reporters on condition of anonymity in the Austrian capital, where talks between the United States, Britain, France, Germany, Russia, China and Iran have entered their final phase.
