N-talks with Iran constructive: Western source

GENEVA: Talks Monday between world powers and Iran were "constructive" and held in a "good atmosphere", a Western source told media after the first day of negotiations over Tehran's disputed nuclear programme.

The discussions were "good, constructive, and held in a good atmosphere," said the source, adding that a number of subjects were addressed, "including the nuclear dossier."

"If the negotiations have carried on for such a long time, it was because there were things to talk about," added the source.

Talks began at around 10:00 am and ended approximately nine and a half hours later.
