A US military official has said that at least 50,000 fighters of ISIS have been killed in Iraq and Syria in the last two years, the BBC reported.

He then went onto state that the number of dead is a “conservative estimate”.

“I am not into morbid counts but that kind of volume matters, that kind of impact on the enemy,” he continued.

As recently as August, Liutenant General Sean MacFarland stated to AP News Agency that around 45,000 ISIS had been killed at that point.
