Western intelligence sees "small sign of wavering" from Iran on nuke policy

…The European Union on Friday provisionally approved substantial new economic sanctions against Tehran.

Despite stalled talks between Iran and a six-country alliance of Western powers, including the United States, a Western diplomatic source said contact with Iranian officials has been sustained consistently, including during the months since the summer.

The official told NBC News there are some signs of “tension within the Iranian regime” over the issue.

“We’ve picked up some small signs of wavering on the nuclear policy,” the official, who did not want to be named, said. “But I don’t want to exaggerate it.”
