BAGHDAD (AP) - Iraq's wave of bloodshed sharply escalated Monday with more than a dozen car bombings across the country, part of attacks that killed at least 95 people and brought echoes of past sectarian carnage and fears of a dangerous spillover from Syria's civil war next door.
The latest spiral of violence - which has claimed more than 240 lives in the past week - carries the hallmarks of the two sides that brought nearly nonstop chaos to Iraq for years: Sunni insurgents, including al-Qaida's branch in Iraq, and Shiite militias defending their newfound power after Saddam Hussein's fall.
But the widening shadow and regional brinksmanship from Syria's conflict now increasingly threaten to feed into Iraq's sectarian strife, heightening concerns that Iraq could be turning toward civil war.
The Shiite-led government of Prime Minister Nouri al-Maliki must balance its close ties with Iran - the main regional ally of Syria's Bashar Assad - and its position among fellow Arab League members and neighboring Turkey, which strongly back Syria's mainly Sunni opposition.
Al-Maliki appears determined to boost security crackdowns to keep Iraq's minority Sunnis from taking a more high-profile role in the anti-Assad forces, which have received pledges of support from the longtime insurgent group al-Qaida in Iraq.
There have been no claims of responsibility for the current flare-up of violence, capped by Monday's body count that was the highest death toll for a single day in 10 months. Yet some analysts believe it's difficult to separate Iraq's deep sectarian suspicions from the Shiite-Sunni split over Assad, which has also led to clashes in Lebanon.
"Iraq now has moved into a bigger circle that covers Syria and Lebanon," said Baghdad-based political affairs analyst Hadi Jalo.
The U.S. and its Western allies strongly support Syria's political opposition, but have been reluctant to significantly boost weapons flow to rebel fighters because of worries over Islamic militants who have joined the anti-Assad brigades. But the deepening refugee crisis in the region, along with concern over spillover violence, is often cited by Arab states and Turkey urging greater Western intervention.
Hours after Monday's stunning blitz of attacks - stretching from north of Baghdad to the southern city of Basra - al-Maliki accused militant groups of trying to exploit Iraq's political instability and vowed to resist attempts to "bring back the atmosphere of the sectarian war."
He also blamed the recent spike in violence on the wider unrest in the region, particularly Syria.
"You cannot remove the Syrian element from what's happening in Iraq," said Sami al-Faraj, director of the Kuwait Center for Strategic Studies. "The outcome of the war in Syria has big consequences for both Iraq's Sunnis and Shiites. What we see now is an extension of that in some respects."
The worst of Monday's violence took place in Baghdad, where 10 car bombs ripped through open-air markets and other areas of Shiite neighborhoods, killing at least 48 people and wounding more than 150, police officials said.
In Balad, about 50 miles north of Baghdad, a car bomb exploded next to a bus carrying Iranian pilgrims, killing 13 Iranians and one Iraqi, a police officer said, speaking on condition of anonymity because he was not authorized to brief the media.
Meanwhile, in the predominantly Shiite city of Basra in southern Iraq, twin car bombings - outside a restaurant and at the city's main bus station - killed at least 13 people and wounded 40, according to provincial police spokesman Col. Abdul-Karim al-Zaidi and the head of the city's health directorate, Riadh Abdul-Amir.
