Mir Hossein Mousavi says the president’s actions on the world stage, such as a speech at the UN last month in which he questioned 9/11, have helped deepen Iran’s isolation.

The pro-reform politician, who ran against Ahmadinejad in last year’s election, says the president’s policies don’t represent the views of the Iranian people.

Mousavi made the remarks Tuesday on his website, Kaleme.com.

Mousavi claims he was the rightful winner of the 2009 vote but that he was robbed of victory through fraud. Hundreds of thousands of Iranians protested the official results.
