Smoke rises from an airstrike during a battle between Iraqi forces and ISIS militants in western Mosul, Iraq, May 21, 2017.

:: A US strike targeting ISIS fighters in a Mosul building in Iraq in March killed at least 105 civilians when the blast caused ISIS weapons to explode, a US general said Thursday.

“The secondary explosion triggered a rapid failure of the structure which killed the two ISIS snipers, 101 civilians sheltered in the bottom floors of the structure and four civilians in the neighboring structure to the west,” US Air Force Brigadier General Matt Isler said of the March 17 incident.

“An additional 36 civilians who are believed to be connected to the structure remain unaccounted for.”
