More than 50 people have been killed in a day of bombing attacks throughout violence-ridden Iraq, officials say, Press TV reported.
At least 47 people were killed in crowded markets in a number of Shia districts of the capital Baghdad on Wednesday.
Three Shia Muslims, who had volunteered to fight against the ISIL Takfiri militants, were killed on a road between the town of Samarra and Mosul, a police official said.
Six dead bodies were also found in the rural district of Taji, 20 kilometers (12 miles) north of the capital, as they were handcuffed and shot in the head and chest in an apparent execution.
Some 2,400 deaths were recorded in June when the ISIL launched a massive blitz capturing parts of the country.
The ISIL Takfiri militants took control of Mosul, in a lightning advance on June 10, which was followed by the fall of Tikrit, located 140 kilometers (87 miles) northwest of the capital.
More than a million people have been displaced in Iraq so far this year, according to the United Nations.
The ISIL has vowed to continue its raid towards Baghdad. Iraqi Prime Minister Nouri al-Maliki has said that the country's security forces would confront the terrorists, calling the seizure of Mosul a "conspiracy".
Soldiers of the Iraqi army have been engaged in heavy fighting with the militants on different fronts and have so far been able to push back militants in several areas.
Maliki has said Saudi Arabia and Qatar are responsible for the security crisis and growing terrorism in his country, denouncing the Al Saud regime as a major supporter of global terrorism.
