Islamic State says it was behind a bombing in Iraq, which has killed more than 70 people.

Hundreds more were injured when a refrigerated truck packed with explosives blew up in a crowded market.

It happened in the Sadr City neighbourhood in north-eastern Baghdad.

At least 86 people were wounded in the attack which occurred at one of the city's wholesale food markets.

"A refrigerator truck packed with explosives blew up inside Jamila market at around 6am," said one police officer.

"Many people were killed and body parts were thrown on top of nearby buildings."

One witness described seeing fruit and vegetables covered with blood.

It is one of the largest attacks on the Iraqi capital since Prime Minister Haider al-Abadi took office a year ago.

Mr Abadi came to power following the collapse of the army when IS took over the northern city of Mosul.

That has left the government relying on Shia forces to defend Iraq's capital city and recapture lost land.

Government-supporting forces are currently trying to remove IS fighters from the Sunni heartland of Anbar in western Iraq.
