In Baghdad, crowds of anti-government demonstrators thronged Tahrir Square, the epicentre of their movement.
There were over a dozen knife attacks by the late afternoon when protesters aligned with political parties and Iran-backed militias withdrew from Tahrir, three demonstrators and a witness said.
On Wednesday, the situation escalated in southern Iraq, prompting the authorities to declare curfew in the Najaf province, where the protesters set the Iranian consulate building on fire.
The leaderless, economically driven protests are targeting Iraq's entire political class and calling for the overhaul of the sectarian system established after the 2003 U.S.-led invasion.
More than 200 people have been killed and 8,000 wounded, the majority protestors, since the movement erupted on October 1.
Around 70 per cent of the deaths were caused by bullet wounds 'to the head or chest', according to the findings published, as Iraq braces for fresh protests on Friday.
The fatalities included 31 protesters and three security officers, as clashes erupted between demonstrators and security forces,
