The U.S. government has released the numbers for civilians killed by counterterrorism strikes outside combat zones during President Obama's tenure.
Its estimate? Between 64 and 116 deaths in 473 strikes.
But that's not the only estimate.
The Bureau of Investigative Journalism estimates between 380 and 801 civilians were killed in 504 strikes.
Neither estimate includes Afghanistan, Iraq or Syria.
"And before any strike is taken, there must be near-certainty that no civilians will be killed or injured — the highest standard we can set," Obama said during a speech at National Defense University in 2013.
The fact the U.S. estimate varies by so much shows how hard it is, even for the government, to keep track of civilian deaths in these kinds of strikes.
