In January 2016, the United Nations Assistance Mission in Iraq reported that it had learned of a major civilian casualty incident in Mosul on June 8th 2015, though had been unable either to verify the claim or attribute responsibility to any party:

“On 8 June, local sources reported that an airstrike in Mosul, Ninewa, caused 33 civilian casualties. The report alleged that several residential neighbourhoods in al-Zuhour district were hit, killing 20 civilians, including seven children and nine women, and wounding 13 others, mostly women. The source claimed that there were no ISIL members in the affected neighbourhoods. UNAMI/OHCHR was unable to verify the status of all the casualties nor who was responsible for the airstrikes.”

In December 2018 the Coalition announced that it had classed the event as non-credible, noting: “June 8, 2015, near Mosul, Iraq, via Airwars report. After a review of available information and strike video it was assessed that there is insufficient evidence to find civilians were harmed in this strike.”

Erem News had reported at the time (June 24th) that “A security source said on Wednesday the killing of 23 Iraqis and wounded 21 others in the bombing of the international coalition aircraft on civilian houses in the city of Mosul, 400 km north of Baghdad. The source said that the international coalition aircraft bombed civilian homes in the areas of Al Zehur and Tahrir, banks, Rifai and Hermat in Mosul, killing 23 civilians, including 10 women and eight children and injured 21 civilians, most of them older men and women and children.”

The local time of the incident is unknown.
