The Pentagon is set to release a report on a U.S. airstrike targeting ISIS fighters in Mosul, Iraq, earlier this year that killed more than 100 civilians.
The report is expected to say the building that was hit either was used to store bombs or was rigged with explosives, NPR's Tom Bowman reports. However, rights groups have accused the U.S.-led coalition of not taking adequate precautions to protect people in Mosul.
The strike took place on March 17; the Defense Department's report is due to be released Thursday.
