Local press sources and relatives of victims reported that 21 or more people, including an elderly woman with her two sons and a displaced family, were hit by a rocket. All victims were still under the rubble in Al-Mahatta neighborhood in West Mosul. The Coalition later accepted responsibility for 11 deaths in the attack.

Mosul Eye initially reported: “Their family members called the Golden Brigade for the rescue but no one has showed up to rescue them. The family is under huge distress

The house location: 36°19’49.3″N 43°06’01.5″E (36.330361, 43.100417) – Near Monastery of Saint Catherine Of Nuns. Please, Attend this as soon as possible”

The group later said all had died.

The Los Angeles Times later visited the scene: “The Times also visited a residential compound in west Mosul’s Mahata neighborhood, where survivors said a March 13 airstrike killed at least 21 people, including four children, in three houses that were reduced to a heap of crumbling concrete. Survivors said they had not been contacted by Iraqi or coalition authorities, and the strike was not mentioned in Sunday’s report. Scrocca said the coalition is investigating. ‘My house has been destroyed by an airstrike and that is very clear,’ survivor Shahab Ahmed Aaid, 25, said on Sunday. ‘All my neighbors are witnesses. I want the coalition and U.S. to investigate and be fair about it.’

In its September 2017 casualty report the Coalition accepted responsibility: “During a strike on an ISIS VBIED, it was assessed that 11 civilians in an adjacent structure were unintentionally killed by secondary explosions from the VBIED.”

Coalition officials told Airwars that this related to an incident at Mahatta, with coordinates [36°19’49.3″N 43°06’01.5″E] which exactly matched this event.

The local time of the incident is unknown.
