Mousavi's supporters have participated in massive rallies in Tehran and other cities over the past four days.

Since Tuesday afternoon, foreign journalists have been banned from covering events on Iran's streets and they are forced to work only in their offices.

According to a statement posted on his website on Wednesday, Mousavi also called on his supporters to stage a peaceful mourning rally or gather in mosques on Thursday.

The statement called on his supporters to express their sympathy with the families of the killed or wounded people in the post-election unrest.
