Bombs hit Iraq's capital Baghdad and a village near the northern town of Baquba on Wednesday, killing at least 75 people, police and hospital sources said, as Prime Minister Nouri al-Maliki warned that militants were trying to set up an "evil statelet".

In the deadliest incident, a bomb blew up in a funeral tent where mourners were marking the death two days ago of a Sunni Muslim pro-government militiaman. It killed 18 people and wounded 16 in Shatub, a village south of Baquba.

In northwestern Iraq, assailants detonated roadside bombs near a bridge in Ain al-Jahash as an army patrol was crossing it. Six soldiers were killed and eight people were wounded, six of them civilians, police said.

Gunmen killed seven truck drivers, kidnapped two and set three trucks ablaze in the mainly Shia district of Maamil in Baghdad's eastern outskirts.

Two years after US troops left Iraq, violence has climbed back to its highest levels since the Sunni-Shia bloodshed of 2006-2007, when tens of thousands of people were killed.

The army is locked in a standoff with Sunni militants who overran Fallujah, a city west of Baghdad, more than two weeks ago in a challenge to Maliki's Shia-led government.

They are led by the al-Qaida-linked Islamic State of Iraq and the Levant (ISIL), which is fighting in western Iraq and Syria to carve out a cross-border Islamist fiefdom.

"The battle will be long and will continue," Maliki said on state television, calling for world support. "If we keep silent it means the creation of evil statelets that would wreak havoc with security in the region and the world."

Maliki has ruled out an assault on Fallujah by the troops and tanks ringing the city of 300,000, but has told local tribesmen to expel ISIL, which has exploited anger among minority Sunnis against a government they accuse of oppressing them.

Al-Qaida loyalists are pursuing a relentless campaign of attacks, mostly aimed at security forces, Shia civilians and Sunnis seen as loyal to the Shia-led government.

The violence has dismayed leaders of Iraq's autonomous Kurdish region. "This is a disaster," its president's chief of staff Fuad Hussein said. "Now the whole country is being threatened by terrorists, so we need to have a common front."

At least eight bombs struck the Iraqi capital, mostly in Shia districts, killing 40 people and wounding 88, police and medics said. A car bomb in Dujail, a Shia town 31 miles north of Baghdad, killed three people and wounded seven.

The bombings followed attacks that cost at least 24 lives the day before, as well as coordinated assaults by militants on a highway bridge and police station near Fallujah.

A suicide bomber in an explosives-laden fuel tanker blew it up under the bridge near the town of Saqlawiya, about six miles north of Fallujah, causing the bridge to collapse and destroying one of two army tanks parked on top, police said. Gunmen then attacked and destroyed the second tank.

Simultaneously, dozens of militants stormed a police station in Saqlawiya, whose occupants surrendered. Helicopter gunships attacked the police station, but failed to evict the militants.

The gunmen withdrew towards Fallujah on Wednesday, making use of a corridor the army had left for civilians. Troops and tanks then retook the police station, turning it into an army base, and civilians living nearby fled towards Fallujah, police said.

The wrecked bridge spans the main road leading west from Baghdad across the vast Sunni desert province of Anbar towards Syria and Jordan. Police said the truck bomber had driven from Ramadi, the provincial capital of Anbar.
