Iraq has now been without a government for six months following its inconclusive elections on 7 March. No end is yet in sight to the political deadlock.
Vice president Adel Abdul Mekdi is warning that voters are losing faith in politics.
Oil and electricity minister Hussein al-Shahristani told the BBC that insurgents were exploiting the failure to reach a power-sharing agreement.
Despite improvements in recent years, attacks remain a daily reality, killing hundreds each month.
On Sunday, insurgents attacked an army base in Baghdad, killing 12 people.
American soldiers were called in to help Iraqi forces fight the insurgents, in the first such use of US troops since the end of the US combat mission on 31 August.
Voters went to the polls on 7 March, but returned a hung parliament.
Politicians still cannot decide who should form the next government.
Feisal Istrabadi, Iraq's former ambassador to the UN, blames the politicians for the deadlock.
"The problem is that the various political actors are attempting to secure their own place in government, rather than to think about the larger needs of the country," he told the BBC's Today programme.
"Even if government were magically formed tomorrow, the ordinary citizen is completely disaffected.
"They have seen no benefit whatsoever for all the heartache and turmoil that they have gone through over the past eight years," he added.
