The US has repeatedly accused Iran of interfering in neighbouring Iraq, including providing weapons and training to Shia armed groups.
US military officials and Iranian exiles have also claimed that there is increasing evidence that many of the most sophisticated roadside bombs being used against US and Iraqi troops are produced in Iran.
In an appearance of state-run Iraqiya television on Saturday, Al-Maliki avoided naming Muqtada al-Sadr’s Mahdi Army as a target of the increased military activity following the announcement.

“Our strategy that aims to control security is based on using force against any outlaws whatever their background or identity,” al-Maliki said.
Al-Maliki has repeatedly used that kind of formulaic language during his eight months in office, but has routinely blocked American forces from taking on his militia allies.
He told a small group of Iraqi reporters that “what we have seen in the American strategy is that it is identical to our strategy and our intentions”.
Meanwhile, Egypt and Saudi Arabia have warned that reconciliation and national unity in Iraq are necessary for the success of Bush’s new strategy.
Suleiman Awaad, the Egyptian presidential spokesman, told reporters on Saturday that Egypt wants “everybody to comprehend … that a national reconciliation is the necessary condition and obligation for this process to succeed.”
