Doctor Abdel Hassan al-Jabri said the bodies of the seven men were handed over on Monday to the morgue of the state hospital of Nassiriya, the provincial capital.

They had been tried and convicted on charges of "terrorism", he said.

In December last year Iraq declared "victory" over the Islamic State group after a three-year war against the jihadists who once controlled nearly one third of the country.

In June, Iraq executed 13 jihadists after IS claimed responsibility for the murder of eight civilians.

Iraq has repeatedly faced criticism from international human rights groups over the high number of death sentences handed down by its anti-terrorist courts.

In 2017, at least 111 convicts were hanged in Iraq and this year 44 people have been executed.
