Killing more civilians?

A nonprofit monitoring group, Airwars, reports that in the first seven months of the Trump administration thus far more civilians have been killed than under the entirety of the Obama administration. The claim is that 2,300 to 3,400 civilians were killed in the 8 years of Obama. In the first seven months of the Trump administration, they estimate that coalition air strikes have killed between 2,800 and 4,500 civilians.
