Dozens dead as bomber detonates explosive vest inside tent where Shia faithful were commemorating day of Ashura.
A suicide bombing targeting a funeral gathering in northern Baghdad killed at least 35 people and left another 63 wounded, Iraqi police and hospital officials said.
The attack occurred at around lunchtime, the officials said, speaking on condition of anonymity because they were not authorised to brief the media.
There was no immediate claim of responsibility for the attack, but the Islamic State of Iraq and the Levant (ISIL, also known as ISIS) group frequently carries out suicide bombings targeting members of Iraq’s Shia majority, whom it considers heretics.
In the past the ISIL group has increased attacks inside government-held territory far from the front lines after suffering territorial losses on the battlefield, including one on October 9 that killed at least five people, and two more earlier in the month that left at least 10 dead.
Iraq has seen several bombings in recent months, though most have had lower death tolls than Saturday’s attack.
In July, a massive car bomb in central Baghdad’s popular shopping district of Karradah killed about 300 people and forced the resignation of the country’s interior minister.
On Friday, the ISIL crushed a rebellion plot in Mosul led by one of its commanders who aimed to switch sides and help deliver the city to Iraqi forces.
ISIL executed 58 people suspected of taking part in the plot after it was uncovered last week.
Residents, who spoke to Reuters from some of the few locations in Mosul that have phone services, said the plotters were killed by drowning and their bodies were buried in a mass grave in a wasteland on the outskirts of the city.
Iraqi officials say a massive ground assaultcould begin this month, backed by US air power, Kurdish security forces and Shia and Sunni irregular units.
The United Nations says the operation could create the biggest humanitarian crisis in the world, in a worst case scenario uprooting up to one million people.
