At least eight people were killed and dozens wounded after a series of mortar bombs exploded in a busy commercial district of Baghdad, in other incidents on Wednesday
The mortar attacks, which took place in a central market and the southern town of Suwayra, came on the day at least 75 Iraqis were killed or found dead across the country, including 48 whose bullet-riddled bodies were found in different parts of the capital.
Elsewhere, two people were killed when a suicide bomber blew himself up on a minibus travelling through the predominantly Shia, Sadr City, Thaer Mahmoud, a police spokesman said. Another 15 were wounded in the attack.
A bomb also exploded in the town of Iskandariya, south of Baghdad, killing four, police said.
In a western Baghdad district, armed men attempted to assassinate Brigadier-General Mohsen Qassim, the head of the security force of Iraq's Sunni-controlled ministry of higher education, but only killed his driver.
Wednesday's violence follows the killing of 30 people in central Baghdad on Tuesday.
Armed men killed 14 employees of a Shia religious foundation in the Iraqi capital, while three car bombs killed 16 people in a separate attack near a petrol station in a religiously mixed area.
The employees of the Shia foundation were killed when their bus was ambushed, Salah Abdul Razzaq, a spokesman for the organisation said.
Interior ministry sources said the attackers first set off a car bomb and then sprayed the bus with bullets on a highway in northern Baghdad.
Three car bombs were detonated in sequence in the attack on the petrol station in southwest Baghdad.
The explosions occurred in Biyaa, a mixed Sunni Arab and Shia section of the city.
