Iraqi Prime Minister Haider al-Abadi has sacked a number of electricity ministry officials, his office said on Thursday, in the latest attempt to quell public anger at chronic power cuts.
May's parliamentary election was marred by low turnout and allegations of fraud.
An alliance headed by nationalist cleric Moqtada Sadr and a rival bloc of pro-Iranian former fighters appeared to surge on Monday in surprise preliminary results from Iraq's first poll since the defeat of the Islamic State group.
The Iraqi air force carried out a new strike on an Islamic State position inside Syria, Prime Minister Haider al-Abadi's office said in a statement on Sunday.
There was no immediate claim of responsibility, but most such attacks in Iraq are the work of the Islamic State jihadist group.
Haider al-Abadi's newly created "Victory Alliance" will face the "State of Law" bloc of Nuri al-Maliki, his predecessor, key rival and Shia Dawa party co-member who now holds the post of vice president.
Haider al-Abadi has said he will not declare the jihadists have been defeated until they have been cleared from the dry valleys and other natural hideouts that have provided them with a desert refuge.
