Two people were killed at a banned opposition rally in Iran, a member of parliament told the student news agency ISNA.
"At Monday's rally...two people were martyred and many were wounded; one person was shot dead," Kazem Jalali was quoted as saying by ISNA.
Thousands of Iranian opposition activists rallied on Monday in support of popular uprisings in Egypt and Tunisia.
A senior police official said one person was killed and several wounded by protesters.
An opposition website said at least 1,500 people were arrested while taking part in the banned protests. The protests amount to a test of strength for the reformist opposition which took to the streets in mass protests in 2009.
