Iran has executed two people over widespread street unrest that erupted after the Islamic Republic's disputed presidential election in June, an Iranian news agency reports.

The two were among 11 people who had been sentenced to death on charges including moharebeh (waging war against God), efforts to overthrow the Islamic establishment and membership of armed groups, the ISNA students agency said.

The executions were the first carried out for election-related incidents.

The presidential election plunged Iran into its deepest internal crisis since the 1979 Islamic revolution.

"The sentences against two of these people ... was carried out today at dawn and the accused were hanged," ISNA said.

It named the two as Mohammad Reza Alizamani and Arash Rahmanipour.
