Khamenei hails Obama "window of opportunity" on Iran

"We heard two days ago that the US president said that (they) are not thinking about war with Iran. These words are good words and an exit from delusion," Khamenei was quoted by IRNA as saying.

But Khamenei said Obama had also spoken about bringing "the Iranian people to their knees through sanctions. This part of his comments shows that the illusion continues".

The United States and European allies have expanded economic sanctions against the Islamic Republic to get it to rein in its disputed nuclear programme.
