Two more attacks occurred late on 23 July 2012, increasing the number of attacks to thirty-two.
Rod Nordland stated that the number of attacks was forty.
The major targets of the attacks were security forces, government buildings and Shia Muslim neighbourhoods.
The first attack took place on an army base in Saladin Governorate
, nearly 20 miles (32 km) north of Baghdad, a series of bombs around a number of homes went off simultaneously; as police arrived and residents began searching the wreckage for survivors, a suicide bomber
detonated himself, killing more.
At least 41 people were killed in this attack, considered the worst of the overall event.
A car bomb exploded near a government building in Sadr City
in Baghdad, killing 16. At least five car bombs went off in Kirkuk

In al-Husseiniya, a predominantly Shiite suburb in northeastern Baghdad and in Mosul
, a total of six people were killed in bombing attacks.
Explosion in Yarmouk
, another neighborhood of Baghdad, killed at least four people and injured another 24.
Nearly five people were also killed and 22 or 25 injured when a car bomb exploded near a busy market in Diwaniya.

The second was a roadside bombing near Baquba
, a city northeast of Baghdad. The second blast killed three people and injured seven others.
Though no group claimed responsibility immediately after the killings, the attacks were believed by Iraqi officials, media and specialists to be orchestrated by Al Qaeda
, seeking to gain control of the country following the departure of the American forces.
An announcement purported to be from Abu Bakr al-Baghdadi
, the current leader of al-Qaeda in Iraq known as the Islamic State of Iraq
(ISI), had been broadcast on 21 July 2012; in the announcement, al-Baghdadi declared the intention towards a new offensive to retake the country, a move claimed to be supported by the Sunni population of Iraq.
Previous attacks that have targeted the security forces have been attributed to al-Qaeda.
On 25 July 2012, the Islamic State of Iraq posted a statement on radical Islamist websites, indicating that it was responsible for the recent attacks, calling the attacks "Destroying the Walls" campaign. ISI also stated that it was just the start of a "new stage of jihad".
