伊核谈判最后期限临近,克里仍抱希望

Secretary of State John Kerry says he is hopeful the U.S. and group of five other world powers can reach a deal with Iran on the country's nuclear program, but that he will not make any predictions.

Negotiators from Iran and the so-called P5+1 group that includes the U.S., Britain, China, France, Russia and Germany are meeting again Tuesday in Vienna. 

They have less than a week to reach an agreement before their November 24 deadline.

Speaking Tuesday alongside British Foreign Secretary Philip Hammond, Kerry called this week's talks "critical."

Iranian media quoted Foreign Minister Javad Zarif saying Tuesday that a deal is still possible and expressing caution toward the international side to not make "excessive demands" of Iran.
