Gun and auto bomb attacks have killed at least 50 people in southern Iraq, officials said Thursday.
"The toll has now reached 50 dead and 87 wounded", Abdel Hussein al-Jabri, deputy health chief for the mainly-Shia province of Thi Qar of which Nasiriyah is the capital, told AFP news agency.
The terror group claimed responsibility for three suicide attacks, in which suicide bombers targeted a police checkpoint and two restaurants on a highway near the city of Nassiriya.
"We also express our condolences to the fellow peoples of Iraq and Iran", said the ministry statement.
The Islamic State said it was behind both via its news outlet Amaq.
Abdel Hussein al Jabri, deputy health chief for Thi Qar, warned the number of dead could rise as numerous wounded were in a serious condition.
That was followed by blasts caused by two suicide bombers, including one driving a vehicle full of explosives, Thi Qar governor Yahya al Nassiri said.
The governor of Iraq's southern Thi Qar province, where Nassiriya is located, said the death toll was 45.
Bomb attacks in southern Iraq, where the bulk of the country's oil is produced, are relatively rare. It leads to the holy cities of Najaf and Karbala and is often used by Iranian Shi'ite pilgrims.
According to the UN Assistance Mission for Iraq (UNAMI), a total of 125 Iraqi civilians lost their lives, and 188 others were injured as a result of terrorist attacks and other acts of violence across Iraq in the month of August.
