Three car bombs in Baghdad, including a huge blast at a market, killed at least 94 people Wednesday, the bloodiest day in the Iraqi capital this year.

The attacks were all claimed by the ISIL Takfiri group.

The worst bombing struck the frequently targeted Sadr City area of northern Baghdad at about 10:00 am (0700 GMT), killing at least 64 people, officials said.

The blast set nearby shops on fire and left debris including the charred, twisted remains of a vehicle in the street.

Another suicide car bomb attack killed at least 17 people at the entrance of the northwestern neighborhood of Kadhimiya, which is home to an important Shiite Muslim shrine.

In the Jamea district of western Baghdad, another car bomb went off in the afternoon, killing at least 13 people, an interior ministry official and medics told AFP.

A total of around 150 people were wounded in the three bombings.

ISIL issued an online statement claiming responsibility for all three attacks. It said they were carried out by suicide bombers, giving their noms de guerre.

The UN's top envoy in Iraq, Jan Kubis, condemned the bloodshed.

"These are cowardly terrorist attacks on civilians who have done nothing but going about their normal daily lives," he said.

The US State Department spokeswoman, Elizabeth Trudeau, said Washington "strongly condemns the barbaric attacks."

She said they would "only harden the resolve of Iraqis and the international community to utterly destroy this group and its warped ideology".
