GENEVA Britain's Foreign Secretary William Hague and German Foreign Minister Guido Westerwelle will join six-power talks with Iran over its contested nuclear program on Friday.
The six powers - the United States, Russia, China, France, Britain and Germany - began talks with Tehran on Thursday aimed at nailing down an interim agreement to end a dispute over Iran's nuclear program. U.S. Secretary of State John Kerry has already announced he will participate in the talks to help narrow remaining differences.
Hague announced his participation on Twitter and a diplomatic source confirmed Westerwelle would also attend.
