(Al Jazeera, June 24, 2009) — A former US national security adviser has told Al Jazeera that US intelligence agents are working in Iran.

But Brent Scowcroft said US government support for those in Iran who are protesting against the official results of a recent presidential election would only provoke a more intense crackdown by the government in Tehran.

He told Josh Rushing, the host of Al Jazeera’s programme Fault Lines, that the Obama administration has taken the correct approach in dealing with the unrest in Iran.
