A bombing on Baghdad's southern outskirts killed seven people Wednesday, the latest in a three-day wave of bloodshed targeting Shiite Muslims that has left 113 dead amid fears Iraq is slipping back into all-out sectarian war.
The surge in violence also wounded more than 300 others, and comes as the country grapples with a protracted political stand-off and months of anti-government protests, with analysts warning the deadlock is unlikely to be resolved at least until general elections due next year.
No group has claimed responsibility for the killings, but Sunni militants linked to Al-Qaeda often target Shiites, whom they regard as apostates.
In the latest attack, a bomb went off in the Nahrawan area of southeast Baghdad on Wednesday morning, killing seven people and wounding at least 14 others, security and medical sources said.
It came after a wave of bombings and shootings across Iraq a day earlier killed 57, with 49 others having died in violence on Monday.
And, according to one lawmaker, the situation is unlikely to get any better as Iraq heads into Ramadan, traditionally a month when insurgents look to step up their attacks.
"Nothing will change," Hassan Jihad, a Kurdish MP on parliament's security and defence committee, said.
"This month will not be better because the security forces will carry out the same routine, there will be no change in their activities."
And "they (militants) will continue to show that they are everywhere, that they can reach any place."
The worst of Tuesday's violence struck Baghdad, with at least six car bombs hitting markets and commercial areas in predominantly Shiite neighbourhoods, leaving 42 people dead and more than 100 wounded.
Four others were killed in shootings in the capital, while bombs were also set off in the mostly-Shiite southern cities of Basra, Amara and Samawa, as well as the Sunni Arab cities of Abu Ghraib, Kirkuk, Baquba and Mosul.
Tuesday's violence came a day after a series of attacks north of Baghdad left 49 people dead, among them 23 in a suicide bombing at a funeral in a Shiite religious hall.
The United Nations has said that more than 2,500 people were killed in a surge of violence from April through June.
Figures, meanwhile, showed the death toll in that time was more than twice that of the first three months of the year.
Attacks in recent months have targeted a wide cross-section of Iraqi society -- government buildings and security forces were hit by car bombs, mosques were struck by suicide attackers, anti-Qaeda militiamen were shot dead, and Iraqis watching and playing football were killed by blasts.
Many of those attacks have struck Baghdad, but shootings and bombings have also been concentrated in the Sunni Arab north and west of the country.
The surge in violence comes amid a protracted political standoff within Iraq's national unity government.
While political leaders have pledged to resolve the dispute, with Prime Minister Nuri al-Maliki meeting his two main rivals last month, no tangible measures have been agreed.
Meanwhile, tensions have continued along a swathe of disputed territory in north Iraq, and months of protests among the Sunni Arab community have continued unabated, albeit in smaller numbers since provincial elections earlier this year.
