The attempt upon Al-Kadhimi's life is "a new sedition that must be traced back to foreign think tanks, which have brought nothing but insecurity, discord & instability to oppressed Iraqi people through creation & support of terrorist groups & occupation of this country for years," Shamkhani said on Twitter.
Iraqi prime minister has called on everyone for calm and restraint in his Twitter message.
Early Sunday, a rocket struck the house of the prime minister. An Al Arabiya correspondent reported that Al-Kadhimi was taken to hospital with slight injuries. The prime minister later tweeted that he was fine. Three of his security guards were wounded, according to Iraqi media.
