Tehran and six world powers started their first negotiations in six months over Iran’s nuclear program on Tuesday.

“The talks have started,” Reuters quoted a Western diplomat as saying.

The US, Russia, China, France, Britain and Germany are expected to press Iran over the two-day meeting in Geneva to agree to scale back its nuclear program in return for relief from economic sanctions.

The election of President Sheikh Hasan Rouhani in June has raised hopes in the West that a deal could be possible.
