The Iraqi prime minister has reacted to the arson at a storage site of the ballot boxes from country's recent parliamentary elections.
The fire was confined to one of four warehouses in Baghdad's al-Russafa district, where 60 percent of the capital's 2 million eligible voters had cast their ballots.
Al-Wataniya Coalition, led by Iraqi Vice-President Ayad Allawi, has called for a redo of the parliamentary elections after a fire at a voting ballot warehouse in Baghdad.
"Burning election warehouses.is a plot to harm the nation and its democracy", Abadi said. He said Baghdad will take all necessary measures, and pledged an iron fist policy against those who undermine the country's security.
An interior ministry spokesman told Reuters news agency the blaze had been confined to one of four warehouses.More news: Trump, Kim co-star in U.S.-made summit film mixing propaganda, Hollywood
However, a Baghdad Province council member said that "all the boxes and papers have burned".
But the result was contested following allegations of fraud namely by the veteran politicians led by parliamentary Speaker Salim al-Jabouri.
A fire has engulfed a storage facility in the Rusafa district in Baghdad housing physical ballots from the Iraqi elections held in May 2018.
The ballots in the Al-Russafa warehouse were due to be recounted manually.
One of Sadr's top aides had said on Sunday that the ballot box fire was intended either to force a rerun of the election or to hide fraud.

"The re-run of the elections is a judicial decision", he said.
The fire started hours after a number of judges were officially tasked with carrying out the manual process of recounting the votes from May's election. However, he explained that it is possible ballot boxes were destroyed.
Mr al-Sadr, who emerged as a kingmaker in the elections, has a chequered and sometimes violent past which has included targeting both foreign troops and Sunni Iraqis with violence.
Coupled with the historically low turnout of about 45 percent, the allegations of violations cast an unflattering spotlight on the election - Iraq's first since ISIL took over and subsequently lost almost one-third of the country's territory.
"Is it not time to stand as one for building and reconstruction instead of burning ballet boxes or repeating elections just for one seat or two?" he added. One of Sadr's top aides expressed concern that some parties were trying to sabotage the cleric's victory. The Independent High Elections Commission had used electronic vote-counting devices to tally the results.
Opponents of the recount have pointed out that many of those who voted for it lost seats in the election.More news: Paris on lockdown as 'armed man takes hostages'
