The top diplomats for France and the United States are urging Iran to prove that its nuclear program is peaceful, as time runs out on Tehran's negotiations with world powers.

U.S. Secretary of State John Kerry and French Foreign Minister Laurent Fabius maintained Wednesday that Iran has the right to generate nuclear power - but not enough to create a bomb.

Kerry will meet this weekend with top diplomats from Iran and the European Union in the latest turn of years of negotiations to curb Tehran's nuclear program. Crippling sanctions on Iran's economy has pushed the Islamic republic toward an agreement but ongoing talks are set to expire later this month.

Kerry says it should be "easy" for Iran to prove that its nuclear program is peaceful.
