Anti-government protestors took to the streets on Wednesday across Iraq, including the capital Baghdad, demanding improved living conditions and an end to what they call government corruption, Anadolu Agency reports.
Women also took part in the second day of protests, with security forces on high alert, locking down several squares and streets in Baghdad.
The country's National Security Council held an emergency meeting with Prime Minister Adil Abdul-Mahdi to discuss how to address the protests.
A Health Ministry official in the country's southern province of Dhi Qar told Anadolu Agency that at least four demonstrators were killed there.
The source, who asked not to be named due to restrictions on talking to the media, added that a policeman was also killed in the same province.
Wednesday's casualties bring the number of deaths since the eruption of protests on Tuesday to 10, including a policeman, along with dozens of injuries.
Anti-government protesters set fire to some government buildings in districts affiliated with provinces in southern Iraq.
Hakim al-Asadi, one of the military officers in charge of the Al Rafidain Operations Command, told Anadolu Agency that demonstrators set fire to municipal buildings.
He said five people, including security forces, were injured in the incidents while the security forces tried to remove the demonstrators from a district governor's office.
The UN representative in Iraq, for his part, called on Iraqi authorities to exercise restraint.
