Iranian President Hasan Rouhani (R) delivers a speech during the opening session of the new parliament in Tehran on May 28, 2016.

The Ahlus Sunnah Iranian parliamentary bloc has demanded an investigation into MP Javad Karimi Ghoddousi’s alleged insults of the companions of Prophet Mohammed.

In a letter the bloc submitted to Parliament Speaker Ali Larijani on Saturday, the bloc voiced anger of Ghoddousi’s statements made on Friday “insulting” the four successors of Prophet Mohammed and making “false claims” about Sunnis, the Iranian Labor News Agency reported.

The bloc voiced the importance of investigating Ghoddousi, who is a representative of Mashhad, over the “insults and fabrications” made.

According to semi-official sources, there are between 10 and 20 percent of Sunnis in the country, which has a total population of 79 million.
