Despite US generals' asserting that the so-called "surge" strategy in Baghdad is working, Iraq has witnessed the deadliest attacks against civilians in months.
Dozens were killed across the country in apparent suicide attacks using techniques similar to those during 2006 and 2007 when Iraq appeared on the edge of a sectarian war.
Confrontations between Iraqi and US-led foreign forces and armed opposition groups have also continued to rage across Iraq, putting civilians' lives in increased danger.
Al-Qaeda, which has been on the wane since the launch of al-Sahwa - the Awakening Councils, a tribal militia set up by Sunni Iraqis with US funding to fight it - has resurfaced and its leaders resumed sending messages to the public calling on them to attack "US occupation forces".
Al Jazeera spoke to analysts and those close to the situation to find out if security is deteriorating again after months of relative stability.

"Many parties are interested in keeping Iraq in a state of chaos and instability. There is a serious clash of interests among many Middle Eastern countries when it comes to Iraq.
"We can say there is an intelligence war in Iraq, and those come from countries interested in keeping Iraq a volatile country, and I believe that attacking civilians is the easiest way to shake the situation.
"The US is a player in Iraq's affairs, however, they are not going to stop meddling in Iraq's affairs and really work hard to stabilise the situation in the country until they achieve their goals.
"Until that day, they are going to be a part of Iraq's dilemma."

"Initially, we think it al-Qaeda who performed the recent bombings.
"We do not have solid evidence for that, but the touches and the way of execution refer to al-Qaeda. This organisation, performs such attacks as a propaganda tactic, it wants to frighten Iraqi people and let them live a fear.
"We agree that many parties are interested in keeping Iraq unstable, however, we do not have information there is a war of intelligence services in Iraq.
"Parties that publicly disagree with the Iraqi government are there, such as Iran and those who disobey Muqtada al-Sadr in laying down their arms and participate in building Iraq.
"Those who do not abide by law are many in Iraq, and we should not drop them from our circle of accusation."

"First of all, there is nothing called an improved security situation, all that has happened is the government-backed militias who used to butcher people, were stopped from doing so for tactical reasons.
"As to us, Iraqis and non-Iraqi volunteers who dedicated ourselves to driving the US occupation out of Iraq, we never stopped working, but the US officials like to distract the world with the monster they created, al-Qaeda.
"More than 4,000 US soldiers have been killed in Iraq, who killed them? The resistance of course, but they [the US] do not want to talk about it, they only want to continue crying loud 'al-Qaeda'.
"I can assure you, their surge policy is not working, and will never work."

"As with most developments in US military and foreign policy, the intent is directed more at domestic American public opinion than the situation in the affected area.
"Right now, the war in Iraq is one of the foremost political issues in the run-up to the presidential election this November.
"The US military recognises this fact, and they are already lobbying hard to influence the policies of Republican candidate John McCain and Democrat front runners Barack Obama and Hillary Clinton.
"The message which the top commanders are trying to sell these politicians is that it would be naive to base an election platfom on the premise of an immediate troop withdrawal from Iraq.
"This would undoubtedly be very popular with many voters, but would only result in a regional bloodbath.
"To emphasise the commanders' argument for the ongoing necessity of US troops to stabilise Iraq, we suddenly see a spike in offensive operations.
"The Pentagon is already looking beyond the Bush era, and they are attempting to sell a continued US presence in Iraq to whomever will occupy the White House next January."
