Not this decade, but during the battles of Fallujah we gave the civilians there 24 hours to evacuate, and then after that the official rules of engagement were pretty damn close to "everyone left is presumed to be an Al Qaeda militant." They were allowed to shoot people with phones or radios in their hands on sight. We also bombed the fuck out of that city, including with white phosphorous. We know WP was used because there was a recorded friendly fire incident with it.
And all of this was basically reprisal for the killings of those four Blackwater mercenaries.
A logical and strategic justification. Still a literal warcrime.
