|Attacks raise tensions on eve of Iraq polls||
Twin bombings killed 15 people northeast of Baghdad Tuesday, the latest in a wave of deadly violence that has cast a pall over Iraq's first general election since U.S. troops withdrew.
The bloodshed came a day after a spate of blasts, including 10 suicide bombings, killed 64 people, raising questions over whether Iraq's security forces can protect upwards of 20 million eligible voters during Wednesday's polls.
Prime Minister Nouri al-Maliki, under fire over the worst protracted surge in violence in years along with a laundry list of voter grievances, is bidding for a third term in office in the election, the country's first since 2010.
The premier has trumpeted a battle against terrorists whom he claims are entering Iraq from war-torn Syria and supported by Persian Gulf Arab states including Saudi Arabia and Qatar.
In the latest violence, a spate of attacks on Monday killed 64 people in Baghdad as well as north and west of the capital, fueling fears voters may stay at home rather than risk being caught up in bloodshed.
On Tuesday morning, twin bombings at a market in the town of Saadiyah, northeast of Baghdad, killed 15 more people.
More than 3,000 people have been killed in violence so far this year, according to an AFP tally, including more than 750 already this month.
The unrest is the country's worst since it was plagued by all-out sectarian fighting in 2006 and 2007 that left tens of thousands dead.
Authorities have announced a week-long public holiday to try to bolster security for the election, and vehicles will be barred from Baghdad's streets from Tuesday evening.
No group has claimed responsibility for the latest bloodshed, but militant groups have been accused of carrying out previous bombings in an attempt to derail the political process.
The month-long campaign ahead of Wednesday's vote has centered around Maliki's bid for a third term in office.
The premier contends that foreign interference is behind deteriorating security and complains of being saddled with a unity government of groups that snipe at him in public and block his efforts to pass legislation.
The 63-year-old who hails from Iraq's Shia Arab majority is widely expected to win the largest number of seats in parliament, but is unlikely to win a majority on his own.
He will therefore have to win the support of coalition partners, notably from Kurdish and Sunni parties as well as fellow Shias, in order to form a government.
But with a fractious and divided opposition, analyst say Maliki remains the frontrunner.
Formation of a government could take several months, however, as the country's various political groups typically negotiate the senior positions of prime minister, president and parliament speaker as part of a package.
In previous elections, a de facto agreement has emerged whereby the premier is Shia, the president a Kurd and the parliament speaker a Sunni Arab.
