“We are not going to sit at the negotiating table forever” he said.
Iran and the P5+1 countries - the United States, Britain, France, Russia, China and Germany - have been engaged in crucial talks in Vienna towards reaching a landmark agreement over Tehran’s nuclear program.
The negotiating sides missed an initial deadline of June 30 and all parties agreed on a new July 7 deadline. However, negotiations will continue for "a couple" of more days as some issues remain unresolved.
Kerry emphasized that progress has been made in the talks but tough issues still remained unresolved.
“Let me assure you we would not be here continuing to negotiate for the sake of negotiating,” he said. “We know that difficult decisions don`t become easier over time.”
The top US diplomat said that the US and its negotiating partners are “prepared to call an end to this” if “tough decisions don`t get made.”
