The protester didn't follow through with his plan to burn the Koran in Stockholm, but he still kicked and partially destroyed one.
Iraq told the Swedish ambassador to leave and recalled its own envoy to Stockholm.
This led Sadr to declare last August that he was withdrawing from politics, leaving the Iran-backed Shi'ite groups in the driving seat of government.
Sadr has mostly laid low since announcing his departure from politics, engaging supporters in religious events rather than calling them to the streets for protests.
That has changed after the burning of a Koran in Sweden last month, when Sadr called on supporters to engage in mass demonstrations at the Swedish embassy and other parts of Iraq.
